TL;DR: In this article, an LPCVD polycrystalline silicon layer is placed over the surface of a high-resistivity silicon wafer which is then covered with a silicon dioxide layer.

TL;DR: In this article, numerical simulations are used to study the electromagnetic scattering from phase agile microstrip reflectarray cells which exploit the voltage controlled dielectric anisotropy property of nematic state liquid crystals (LCs).

TL;DR: In this article, a frequency selective surface (FSS) which exploits the dielectric anisotropy of liquid crystals to generate an electronically tunable bandpass filter response at D Band (110-170 GHz) is presented.

TL;DR: This new class of quasi-optical filter exhibits an insertion loss <;0.3 dB at 700 GHz and can be designed to operate independently of the polarization of the incident signals at oblique incidence.

TL;DR: In this article, an offset parabolic reflector antenna which employs a reflectarray sub-reflector to tilt the focused beam from the boresight direction at 94 GHz is described, and numerical simulations are employed to demonstrate that the high gain pattern of the antenna can be tilted to a predetermined angle by introducing a progressive phase shift across the aperture.
