A formulation to deal with materials having dispersive and nonlinear characteristics in the finite-element time-domain method is proposed. The approach is illustrated by an electric discharge simulation in a spark gap switch based on the collision pl

The Newmark formulation for the time-stepping solution of the electric field vector wave equation is modified in order to suppress low-frequency spurious responses. It is verified that the proposed method has the advantage of halving the number of it

A novel structure called ridge coplanar waveguide is proposed for Mach-Zhender optical modulator. Numerical modeling using a two-dimensional finite-difference time-domain (2D-FDTD) algorithm has shown that a ridge coplanar waveguide on Y-cut LiNbO/su

A laterally shielded coplanar waveguide consisting of a coplanar waveguide of finite width placed vertically in a cutoff parallel-plate waveguide is proposed for millimeter-wave applications. Advantages of the waveguide over the conventional coplanar

The design of integrated inductors on silicon has become an important issue to decrease costs and to speed up the fabrication of telecommunication integrated circuits. Nevertheless, the formulae provided by the existing theory still do not show a goo

A laterally shielded coplanar waveguide (CPW) has been proposed for millimeter wave use. It is a CPW sandwiched vertically in a below cutoff parallel plate waveguide and can suppress unwanted waves in circuits. A right angle bend as well as a straigh
