Three-Dimensional Electromagnetic Approach to the Modeling of Time Reversal Technique for Communication

In this paper, we introduce a three-dimensional electromagnetic approach to the modeling of time reversal (TR) technique in communication. The proposed method uses time-domain transmission line matrix (TD-TLM) method for the computation of the channel response in a rich scattering environment. The time-reversed version of the computed channel response is used as the source signal of the transmitting antenna. The electromagnetic solution is repeated and the characteristic of the TR channel is assessed.
