An approximate method to calculate the horizontal electric field at ground level from inclined lightning channel in frequency-domain is proposed based on the extension of Cooray formula. The validation results show that the deviation of the extended formula is closely related to the observation distance and the ground conductivity. The bigger the observation distance or the ground conductivity is,...
Aiming at accelerating the simulation of the lossy reverberation chamber using the finite-difference time-domain method, a fast and accurate approach is proposed. The lumped losses of the real chamber are equivalently substituted by adding the artificial-loss atmosphere, which is evenly distributed throughout the chamber. Unlike the lumped loss, such even loss could reduce the simulation time dramatically...
