Site precise radio wave propagation simulations by time domain finite difference methods

An in-building site-precise radio propagation model based on time-domain finite difference (TDFD) methods is proposed. TDFD methods are the most useful tools for modeling electromagnetic fields in complicated structures. Once the TDFD codes are developed, reading in-site blueprints should allow TDFD programs to predict the fields inside the building accurately. The TDFD methods are discussed. Some simulation results are provided.
