metallic nanoparticles can exhibit very large optical extinction in the visible spectrum due to localized surface plasmon resonance. spherical plasmonic nanoparticles have been the subject of numerous studies in recent years due to the fact that the scattering response of spheres can be analytically evaluated using mie theory. however a major disadvantage of metallic spherical nanoparticles is ...

A versatile precision rectifier based on a current conveyor and current mirrors is presented. The proposed circuit performs positive half-wave, negative half-wave, positive full-wave, and negative full-wave rectification into a single circuit. The current-mode technique has been employed to provide the high-precision capability of the circuit. The circuit configuration is very suitable for inte...

This paper describes a new subgridding approach with a view to improving the efficiency of full-wave simulation of electronic circuits. The proposed subgridding method has been incorporated into a full-wave variable-mesh finite-difference transmission line matrix (FD-TLM) simulator. By incorporating the proposed subgridding method, a speed-up of about 2 has been attained. The computational acce...

in this paper, the operation of helix traveling wave tube in interaction region is investigated by using a three dimensional large signal lagrangian model in frequency domain. the complete simulation of these tubes is essential for optimum design and minimum manufacturing cost. this 3d code can compute interception current (or current losses ), beam radius changes in interaction region and the ...
