Future smart systems for communication and RF-sensing will have to achieve autonomous and self-reconfigurable operations, for real-time and efficient selfoptimization of their performance. The needs for such reconfigurable systems are not only to overcome the design tradeoffs that current analogue components must endure, but also to realize new and more efficient systems with improved functiona...

Millimeter wave technology advances have made possible active and passive millimeter wave imaging for a variety of applications including advanced plasma diagnostics, radio astronomy, atmospheric radiometry, concealed weapon detection, all-weather aircraft landing, contraband goods detection, harbor navigation/surveillance in fog, highway traffic monitoring in fog, helicopter and automotive col...

A historical sketch of microwave integrated circuits, monolithic microwave integrated circuits, and their application is presented in this paper.

Fe(3+) ions in sapphire exhibit an electron spin resonance which interacts strongly with high-Q whispering gallery modes at microwave frequencies. We report the first observation of a third-order paramagnetic nonlinear susceptibility in such a resonator at cryogenic temperatures and the first demonstration of four-wave mixing using this parametric nonlinearity. This observation of an all-microw...

In this paper, an ideal cylindrical metamaterial invisibility cloak with infinite-length which its electric permittivity and magnetic permeability mapped to the Drude dispersion model is simulated. The sinusoidal plane waves with microwave frequencies used as sources. To this end, the dispersive finite-difference time-domain method (FDTD) used with Convolutional Perfectly Matched Layered (CPML)...

Ball lightning that is a natural phenomenon behaves curiously and moves variously according to a huge amount of eyewitness reports. The ball lightning could be reproduced by an alternative experiment that was the result of a localized spherical plasma object (fireball) caused by microwave interference and discharge inside the cavity. In the experiment, the motion of the plasma fireball was exce...

Introduction: The Georgia Tech Venus Radiative Transfer Model (VRTM) can be used to model the effects of the abundances of microwave and millimeter wave absorbing constituents on the emission from the Venus troposphere and mesosphere. The primary components of the Venus atmosphere are CO2 and N2, but variation in concentration of sulfur compounds, specifically gaseous H2SO4 and SO2, result in c...
