Numerical simulations as a tool for optimizing the geometrical design of reverberation chambers

摘要

The Finite Difference Time Domain (FDTD) method is used to simulate the electro-magnetic field in a reverberation chamber. By including conductivity and thickness of the walls in our model a good agreement with measurements is found. With help of the FDTD numerical computation program it is shown that by introducing wall mounted diffusors the minimum operating frequency of the reverberation chamber could be lowered.
