Half Mode Substrate Integrated Waveguide without via

SIW and HMSIW have been proven as one of the best solutions for millimeter-wave waveguide propagation. Fabrication of these structures requires expensive and problematic metalised via construction. In this paper we propose a new method to construct HMSIW without via which eliminate the fabrication difficulties and achieve the same performance. The concept is verified by simulation using CST®

An Experimental Realization of Cylindrical Cloaking using Dogbone Metamaterials

The quest for invisibility has made a deep ardour among research community over the decade. The invention of metamaterials has boosted the research on electromagnetic cloaking due to its unusual electromagnetic parameters under plane wave incidence. In this study, we propose a novel cloaking scheme using the dogbone metamaterials, for effectively routing the incident electromagnetic fields around a target metal cylinder under consideration. Notable reduction in the scattered power is observed from the target in comparison to an uncloaked target. Experiments and simulations validate an effective reduction in the Scattering Cross Section of the target and effective guiding of the incident plane wave around the target.The accepted manuscript in pdf format is listed with the files at the bottom of this page.

Novel Millimeter-Wave Antenna Array Using Half Mode Substrate Integrated Waveguide (HMSIW)

A millimeter wave antenna using Half Mode Substrate Integrated Waveguide (HMSIW) is presented. Narrow rectangular patch is used as radiating element fed by the open end of the HMSIW. Simulation results are presented for antenna array designed on Alumina substrate for 24GHz and 60GHz band
