โœฆ Synopsis

A new absorbing boundary condition using an absorbing layer is presented for application to finite-difference time-domain (FDTD) calculation of the wave equation. This algorithm is by construction a hybrid between the Berenger perfectly matched layer (PML) algorithm and the one-way Sommerfeld algorithm. The new prescription contains both of these earlier ones as particular cases, and retains benefits from both. Numerical results indicate that the new algorithm provides absorbing rates superior to those of the PML algorithm.

## In this work, we present a new absorbing boundary condi-( ) tion for the finite-difference time-domain FDTD method. This boundary condition is based on the use of chiral absorbers, which are well suited for this application. Further, we present seยจeral numerical examples to illustrate the effica

In contrast, in the E-plane, there was a large change across most of the band, with a threshold at about 20 GHz, above which the average was about 150% in the y10 dB width, although there are two prominent peaks at about 20.5 GHz, where the measurements in Figures 1แŽ3 were made, and als

A perturbation method is presented to analytically calculate eigensolutions of the two-dimensional wave equation when asymmetric perturbations are present in the boundary conditions. The unique feature of the method is that the sequence of boundary value problems governing the eigensolution perturba
