The equivalent circuit model for artificial magnetic materials based on various arrangements of split rings is generalized by taking into account losses in the substrate or matrix material. It is shown that a modification is needed to the known macroscopic permeability function in order to correctly describe these materials. Depending on the dominating loss mechanism (conductive losses in metal...

Detection peculiarities of an un-cooled (room temperature) 8×8 pixel array designed to image broadband THz radiation were investigated. Each pixel consists of a thin conductive film absorber on a dielectric membrane with thermopile temperature readout. It was designed and tested for four combinations of two different types of absorber and thermopile materials. The photo-response profile, determ...

•Several materials have been investigated for use in nano-CMOS technology, such as ZrO2, TiO2, BST, HfO2, Al2O3, SiON, and Si3N4. •Intel has recently prototyped a processor called Penryn using such transistors of 45nm technology. •For compact modeling based study of high-K non-classical transistors using BSIM4/5, two possible options can be considered: (i) varying the model parameter in the mod...

Inspired by the design of composite materials, a novel composite supercapacitor is proposed comprising an integrated cell with high powerand high energy-related electrode materials so that the composite electrochemical double layer capacitor (EDLC) is the equivalent circuit of a high power EDLC of power P1 and energy E1 and a high energy EDLC of power P2 and energy E2 connected in parallel. A m...

The optical nonlinearity and excited carrier lifetime in Ge nanocrystals (nc-Ge) embedded in a silica matrix have been investigated by means of single beam z scan and pump-probe techniques with laser pulse duration of 35 ps and 532 nm wavelength. The nc-Ge samples were prepared using magnetron cosputtering and postgrowth annealing at 800 °C. The nonlinear absorption coefficient a2 and refractiv...
