NUMERICAL INVESTIGATION OF THE EFFECTIVE DIMENSIONS OF PERFECT ELECTRIC CONDUCTOR (PEC) IN FDTD SIMULATION

摘要

In this communication, we present an improvement technique for the finite-difference time-domain (FDTD) method, in which an accurate solution can be achieved using a very coarse mesh if a weighted factor of the simulated PEC object dimension is properly selected. A uniform microwave stripline is used to validate the proposed scheme.
