To Kick Against the Pricks: An Examination of the Oresteia and the Acts of the Apostles
The major themes found in the Oresteia and the books of Luke and Acts of the Apostles are compared. By focusing on the similarities found in the themes of Justice, Religion, and New versus Old, the reader may determine if the phrase in question is being used as a literary allusion in the book of Acts of the Apostles to the Oresteia trilogy. The author believes this to be the case and believes that to arrive at a full understanding of the literary meaning of the phrase in question, an understanding of the major themes of the Oresteia is necessary
A FDFD based Eigen-Dielectric Formulation of the Maxwell Equations for Material Characterization in Arbitrary Waveguide Structures
This paper presents a novel numerical scheme for the extraction of di- electric material parameters using the transmission line method. This method is performed by formulating the discretized Maxwell equa- tions as an eigenpermittivity, permeability or an eigenconductivity problem of the considered sample within an arbitrary and generally inhomogeneous filled waveguide cross section. This allows the direct calculation of the desired material parameter by performing only one full wave simulation. Hence, it is very useful if simplified analytical ap- proaches do not provide the aimed accuracy or even fail completely. This procedure will be demonstrated by applying a modified 2D Finite Differences Frequency Domain scheme to the complex permittivity simulation of arbitrary shaped and placed samples within a waveguide cross section

Continuously Tunable W-Band Phase Shifter based on Liquid Crystals and MEMS Technology
In this paper we present a continuously tunable phase shifter realized in MEMS technology. Varactors with liquid crystals as a tunable dielectric layer underneath gold bridges are utilized to build a loaded line phase shifter. Measurements show that the phase shifter has a differential phase shift of 92°, a figure of merit (FoM) of 42 °/dB and an input matching of -19 dB at 76 GHz. The realized phase shifter can be used in combination with MEMS switches in order to build a 360° tunable reflection phase shifter
