Preliminary FDTD results from the anechoic absorber absorbing boundary condition
A novel ABC has been proposed, based on anechoic chamber absorber foam geometry, with specified complex permittivity and permeability. The advantage of this absorbing boundary, based on carbon-loaded anechoic chamber absorber foam pyramids, is that it prevents reflections from much wider incident angles than currently used techniques. Preliminary FDTD (finite-difference time-domain) results on this ABC are presented. A two-dimensional FDTD simulation of an equilateral triangle saw-tooth absorbing layer, with a modulated Gaussian pulse plane wave, is shown.<>
