Application of the PML Absorbing Boundary Condition to the Analysis of Patch Antennas

Abstract

The Berenger Perfectly Matched Layer (PML) absorbing boundary condition is applied to a Finite-Difference Time-Domain analysis of rectangular patch antennas. Both microstrip tine and probe-fed patch antennas are analyzed. The effects of the proximity of the PML regions on the resonant characteristics of the antennas and the mutual coupling between antennas are examined. The computational overhead associated with the use of the PML is also considered. Numerical results are validated by comparisons with measured data.

Application of Perfectly Matched Layer Absorbing Boundary Conditions for Propagation of Surface Wave on the Long Plasma Cable

“…At the first, the constant electron density profile n=10 12 [/cc] has been considered for the calculation and the obtained magnetic field profile φ=rH θ for the r-z plane is shown in Fig. 3.…”

“…Beside these the effectiveness of element size has been studied for some typical cases in our calculation, for example, for the model of constant electron density 10 12 …”

A Modified Perfectly Matched Layer Implementation for Use in Electromagnetic PIC Codes

“…The PML has demonstrated superior performance in a wide range of electromagnetic applications [9][10][11][12] and is attractive for many PIC applications. In contrast to Jost et al [13] we have taken a simple approach which avoids the treatment of particle interactions within the PML medium.…”
