The design and validation of a dual polarization source for waveguide-coupled millimeter and sub-millimeter wave cryogenic sensors is presented. The thermal source is a waveguide mounted absorbing conical dielectric taper. The absorber is thermally isolated with a kinematic suspension that allows the guide to be heat sunk to the lowest bath temperature of the cryogenic system. This approach ena...

Liquid phase deposition (LPD), using CdSO(4) and N,N-dimethyl selenourea, has been used to grow CdSe absorber layer onto single walled carbon nanotube (SWNT) derived back contact substrates. The nanotubes are imbedded in, and penetrate into, the CdSe absorber layer for the goal of enhancing excition dissociation and carrier transport. The Cd : Se film stoichiometry varied between 1 : 1.7 to 1 :...

Our primary goal is to increase the stabilized efficiency of thin film silicon solar cells in the substrate (nip) configuration by using textured substrates and tandem structures, based on amorphous (a-Si:H) and microcrystalline silicon (μc-Si:H). In order to reduce costs of mass-produced thin film solar modules, special attention has been paid in developing processes compatible with plastic fo...

A high ambient contrast ratio display device using a transparent organic light emitting diode (OLED) or transparent quantum-dot light-emitting diode (QLED) with embedded multilayered structure and absorber is proposed and its performance is simulated. With the help of multilayered structure, the device structure allows almost all ambient light to get through the display device and be absorbed b...

In this study, a novel broadband metamaterial (MTM) absorber is proposed, which based on vanadium dioxide (VO 2 ) resonators coated onto flexible polyamide substrate. The VO resonator in the form of quatrefoil and circle-loaded complementary square split ring (CSSRR), fine tuned to operate terahertz range. MTM design simulation were carried out using Computer Simulation Technology (CST) softwar...

because the underlying physiology of pathological tremor in a parkinson's patient is not well understood, the existing physical and drug therapies have not been successful in tremor treatment. different mathematical modeling of such vibration has been introduced to investigate the problem and reduce the existing vibration. most of the models have represented the induced vibration as a sinusoida...

While a broadband metamaterial perfect absorber (MPA) has been implemented and proposed intensively in recent years, an ultra-broadband perfect absorber with polarization selectivity has not been realized in literature. In this work, we propose a configuration of polarization-selective (PS) MPA with ultra-wide absorption bandwidth. The aluminum wire grid is integrated on top of the ultrathin-me...
