A stochastic contour path finite‐difference time‐domain method for uncertainty analysis of metal slot size

open access: yesIET Microwaves, Antennas & Propagation, 2023
A stochastic contour path finite‐difference time‐domain (S‐CP‐FDTD) algorithm is presented for electromagnetic wave propagation in metallic enclosures with uncertain slot size. The correlation coefficient between the field and size of slot was set to one.
