Passive Surface Protects Against Interference From Multipath Propagation
Numerical validation. (a) Simulation model with Rx covered by an MS-based prism structure. The signals from Tx1 and Tx2 effectively simulated the first signal and the time-delayed multipath signal, respectively. (b),(c) The simulated received voltages in (b) the time domain and (c) the polar coordinate system. The polar plot shows the basic shape of the received voltages (see Supplemental Material Note G for harmonic components [27]). The gray numbers near the symbols indicate the voltage values.
