The feasibility of designing a compact-size beam-switching dielectric lens antenna (DLA) with improved angular (scanning) characteristics is investigated numerically using in-house software based on the Muller boundary integral equations and hybrid genetic algorithm. It is demonstrated that joint optimization of the lens shape and feeding array parameters enables one to minimize the directivity...

Results of broadband dielectric spectroscopy (BDS) in Saccharomyces cerevisiae (baker's yeast), in situ as the function of pressure are presented. They show a clear evidence of a threshold to the new pattern of the pressure evolution of the static dielectric permittivity and DC electric conductivity already for Pt  ≈ 200MPa at T = 5 oC and Pt  ≈ 300MPa at T = 25 oC. BDS monitoring versus pressu...

In this paper, for the first time Transmission Line Model (TLM) characterization is used to analyze ESD events in amorphous silicon thin film transistors (a-Si:H TFT). It will be ,shown that, above an ESD degradation threshold voltage, deterioration of electrical characteristics sets in, and that above another ESD failure threshold voltage, dielectric breakdown occurs. Electrical simulations of...

a simple and reliable method for quick estimation of the dielectric constant of a binary solvent mixture is proposed. the validity of the proposed method has been tested for a broad range of binary solvent mixtures

Real time oil quality monitoring techniques help to protect important industry assets, minimize downtime and reduce maintenance costs. The measurement of a lubricant's complex permittivity is an effective indicator of the oil degradation process and it can be useful in condition based maintenance (CBM) to select the most adequate oil replacement maintenance schedules. A discussion of the workin...
