An FDTD Formulation for Wave Propagation in Biological Dispersive Media

A Finite Difference Time Domain (FDTD) scheme used to model the wave propagation in biological dispersive media has been proposed in this paper. FDTD scheme based on the direct solution of time domain Maxwell’s equations has developed and these solutions were approximated by time based linear functions. We are applied FDTD scheme for different dispersive media models such as Cole-Cole, Cole-Dav...

Scattered Field Fdtd Formulations for Debye Dispersive Media

Astract ---New implementation of scattered field FDTD formulations of dispersive material are employed yielding accurate and mathematically compact procedures. This work is based on the application of the Z-transform on the Debye model representing the dispersion in conjunction with the relation between the electric field and the displacement current. The result is an approximate frequency doma...

Title : Piecewise linear recursive convolution for dispersive media using FDTD

Introduced a new method for computing dispersive media using finite difference time domain method by employing the recursive convolution approach to evaluate the discrete time convolution of the electric field and the dielectric susceptibility function. The RC approach results in a fast and computationally efficient algorithm; however, the accuracy achieved is not generally as good as that obta...

Numerical Dispersion and Stability of an Extended FDTD Method Applied to Negative Refractive Index Media Modeling

The analogy between the FDTD Yee cell and a transmission-line network is invoked for the derivation of a scheme that lends itself to the implementation of a negative refractive index medium. Electric and magnetic currents, incorporated in the update equations, represent series capacitors and shunt inductors, which load the implicitly present transmission line network of an FDTD grid in a way th...
