Accurate near-field calculation in the rigorous coupled-wave analysis method

The rigorous coupled-wave analysis (RCWA) is one of the most successful and widely used methods for modeling periodic optical structures. It yields fast convergence of the electromagnetic far-field and has been adapted to model various optical devices and wave configurations. In this article, we investigate the accuracy with which the electromagnetic near-field can be calculated by using RCWA and explain the observed slow convergence and numerical artifacts from which it suffers, namely unphysical oscillations at material boundaries due to the Gibb's phenomenon. In order to alleviate these shortcomings, we also introduce a mathematical formulation for accurate near-field calculation in RCWA, for one- and two-dimensional straight and slanted diffraction gratings. This accurate near-field computational approach is tested and evaluated for several representative test-structures and configurations in order to illustrate the advantages provided by the proposed modified formulation of the RCWA.Comment: 13 pages, 12 figure

Spreading Democracy Everywhere But Here: The Unlikely Prospect of Foreign National Defendants Asserting Treaty Violations in American Courts After \u3cem\u3eSanchez-Llamas v. Oregon\u3c/em\u3e and \u3cem\u3eMedellin v. Dretke\u3c/em\u3e

To squarely address this decisional quagmire, this article examines the binding effect of ICJ orders, entered pursuant to its compulsory jurisdiction, on American courts; earlier decisions of the Supreme Court penalizing foreign nationals for failing to timely raise individual treaty claims; the effect on treaty enforcement in domestic courts after the executive branch’s recent foreign policy decision to withdraw from compulsory ICJ jurisdiction; the current policy disputes dividing the United States and the ICJ; and, the national interest, or lack thereof, in treaty compliance. The article concludes that the government’s current claim that a “long standing presumption” exists to prevent the assertion of individual rights under Article 36 is simply not supported by international law or prior decisions of the Supreme Court

Introduction

Legal educators increasingly use the classroom to import expertise from scientists and social scientists to better prepare law students to engage in specialized and collaborative fields of practice. Indeed, this project grew out of a paper course on Scientific Evidence in Civil and Criminal Cases offered during the spring 2006 semester at the law school. Students heard from accident reconstruction experts, DNA scientists, forensic pathologist and medical malpractice experts. In February 2006, Dr. Aaron Lazare, Dean and Chancellor at the University of Massachusetts, addressed the law school on a cutting-edge legal theory from his recently published book, “On Apology.” Stimulated by this flow of information from scientists and social scientists, the journal staff invited articles from various scientific and non-scientific disciplines in an effort to identify new forensic theories and consider their relevance and possible application to the law

The Convention on Cybercrime: A Harmonized Implementation of International Penal Law: What Prospects for Procedural Due Process?, 23 J. Marshall J. Computer & Info. L. 329 (2005)

The CoE Convention on cybercrime provides a treaty-based framework that imposes on the participating nations the obligation to enact legislation criminalizing certain conduct related to computer systems, create investigative procedures and ensure their availability to domestic law enforcement authorities to investigate cybercrime offenses, including procedures to obtain electronic evidence in all of its forms and create a regime of broad international cooperation, including assistance in extradition of fugitives sought for crimes identified under the CoE Convention. Since there is no internationally recognized legal definition of computer crime, this article briefly presents the generally recognized categories of cybercrime and then proceeds in a presentation of the historical development of International Cybercrime Law as well as the practical impediments to international investigation, enforcement and prosecution including the absence of global consensus on the legal definition of criminal conduct, the transnational character of many cybercrimes and the lack of extradition and mutual legal assistance treaties. A presentation of the CoE Convention provisions follows where special emphasis is given to Procedural Safeguards under the CoE Convention, where it is being noted that while the complicated problem of guaranteeing civil rights protection to citizens living in different cultures and political systems is recognized, no specific minimal procedural guarantees of due process incident to treaty implementation are established, and the methods of collecting evidence under the Convention the CoE Convention which, similarly, do not require the enactment of certain minimal procedures by a party nor do they contain any minimal requirements concerning confidentiality of materials obtained through a production order. Notably, the CoE Convention contains significant restrictive language in the areas of transborder search and seizure and data interception, deferring authority to domestic laws and territorial considerations. The issues of Jurisdiction and Extradition and the relative problems are also being examined as well as the pre-existing mutual legal assistance treaties ( MLATs ) or other reciprocal agreements between parties. Finally the author examines the CoE Convention as a harmonization model and concludes that it does not adequately safeguard procedural due process. Although the decentralized nature of international penal law may explain such flexible harmonization to achieve law enforcement goals aimed at the timely eradication of cybercrime, cybercrime prosecutions will most certainly raise issues relating to concurrent jurisdiction and/or the application of domestic law to foreign nationals especially regarding the means of investigating and prosecuting the conduct. In view of the fact that in its present form, the CoE Convention allows state intrusions into the sphere of individual privacy rights to gather evidence for use in subsequent criminal prosecutions without adequate guarantees of procedural due process, an addition of a Protocol to the treaty is proposed, modeled after the proposed CoE Constitution providing minimal guidelines for procedural due process, extended to citizens of all participating nations

Ruthless Utilitarianism? COVID-19 State Triage Protocols May Subject Patients to Racial Discrimination and Providers to Legal Liability

As the coronavirus pandemic intensified, many communities in the United States experienced shortages of ventilators, intensive care beds, and other medical supplies and treatments. Currently, there is no single national response to provide guidance on allocation of scarce health care resources. Accordingly, states have formulated various triage protocols to prioritize those who will receive care and those who may not have the same access to health care services when the population demand exceeds the supply. Triage protocols address general concepts of \u27fairness under accepted medical ethics rules and the consensus is that limited medical resources should be allocated to do the greatest good for the greatest number of people.\u27 The actual utility of this utilitarian ethics approach is questionable, however, leaving many questions about what is \u27fair unanswered. Saving as many people as possible during a health care crisis is a laudable goal but not at the expense of ignoring patients\u27s legal rights, which are not suspended during the crisis. This Article examines the triage protocols from six states to determine whose rights are being recognized and whose rights are being denied, answering the pivotal question: If there is potential for disparate impact of facially neutral state triage protocols against Black Americans and other ethnic groups, is this legally actionable discrimination? This may be a case of first impression for the courts to resolve
