The authors present a straightforward and effective approach for minimizing insertion loss (IL) of varactor-based frequency-agile microstrip passive circuits, where varactors are employed as elements of variable reversal capacitances to attain reconfigurabiltiy/tunability on circuit characteristics. Technically, the proposed approach mimics the required capacitances using the varactors together with...
Monocrotaline (MCT) is a naturally occurring hepatotoxic pyrrolizidine alkaloid found in plants. This investigation is aimed at furthering the understanding of the role of blood in mediating the transport of MCT and its reactive metabolites in humans. Reactions of monocrotaline and its metabolites, dehydromonocrotaline (DHM), retronecine (RET) and dehydroretronecine (DHR) with human blood plasma,...
We propose a AND logic gate based on photonic crystal with cylindrical silicon structure. It takes advantages of the device sizes are drastically reduced to a scale of a few tens of micrometers and the easy-to-implement logic function. Furthermore, the multi-input AND gate can apply to all-optical Arithmetic Logic Unit (ALU) devices of photon computer in the future.
All-optical logic gate is a basic and crucial element for optical signal processing. In this paper, we propose a 4×2 encoder based on two dimensional triangular lattice photonic crystals composed of cylindrical silicon rods. The main structure of the device is a combination of both line defect Y branch and coupler photonic crystal waveguides. The computational simulation is carried out by using a...
