Abstract: Methods for constructing multi-walled carbon nanotube (MWCNT) antenna arrays, may include: variable doping of the MWCNTs, forming light pipes with layers of variable dielectric glass, forming geometric diodes on full-wave rectified devices that propagate both electrons and holes, using clear conductive ground plans to form windows that can control a building's internal temperature, and generating multiple lithographic patterns with a single mask.

Abstract: A polarimeter for measuring the polarization state of a wideband electromagnetic signal. The polarimeter includes a first antenna for receiving the electromagnetic signal and a modulator. The modulator is interconnected with the first antenna for modulating the electromagnetic signal whereby a modulated electromagnetic signal results which contains a different polarization state for each frequency of the electromagnetic signal and wherein the amplitude of each frequency component of the modulated electromagnetic signal is a function of the particular polarization state of each frequency component of the electromagnetic signal. Also, the modulator may be configured to modulate at a radar frequency. A linear polarizer is also provided which may be configured to pass a first predetermined polarization of the modulated electromagnetic signal through a first output thereof.
