Using WCS-FDTD Method to Study the Plasma Frequency Selective Surface

IEEE Access, 2019
The plasma is very useful to design the dynamically tunable Frequency Selective Surface (FSS) because of its tunable property. But it is difficult to simulate the plasma FSS by using the conventional finite-difference time-domain (FDTD) method, because ...

A novel finite-difference time-domain wave propagator

IEEE Transactions on Antennas and Propagation, 2000
A novel time-domain wave propagator is introduced. A two-dimensional (2-D) finite-difference time-domain (FDTD) algorithm is used to analyze ground wave propagation characteristics. Assuming an azimuthal symmetry, surface, and/or elevated ducts are represented via transverse and/or longitudinal refractivity and boundary perturbations in 2-D space.
