Indoor wireless channel analysis using alternating direction implicit pseudospectral time-domain method

To analyze electromagnetic wave propagation in a building, a pseudospectral time-domain (PSTD) algorithm has been used for a flexible treatment of internal heterogeneous mixture of homogeneous and periodic walls. Unconditionally stable technique, the alternating direction implicit (ADI) scheme, has been developed combining with the PSTD. The electromagnetic reflection and transmission in a periodic arrangement as well as in corner and terminal locations are approached in two-dimensional around 2.40 GHz. Complex indoor environment has been simulated by using the ADI-PSTD technique, results are shown available.
