We analyze the polarization properties of the tilted off-axis dual-reflector submillimeter-wave telescope on the ESA PLANCK Surveyor designed for measuring the temperature anisotropies and polarization characteristics of the cosmic microwave background.

Polarization induced electron populations in III-V nitride semiconductors Transport, growth, and device applications by Debdeep Jena The III-V nitride semiconductors (GaN, AlN, InN) exhibit unusually large electronic polarization fields. These polarization fields can be engineered to achieve carrier confinement, doping, and band engineering in novel ways. This work presents work in engineering ...

A new broadband and dual band circular slot cut modified circular microstrip antenna is analyzed and proposed. The parametric study to analyze the effects of circular slot which realizes broader bandwidth is presented. The circular slot creates two additional resonant modes near the fundamental TM11 mode resonance frequency of the equivalent circular patch and yields bandwidth of 202 MHz (8%). ...
