Some Amendments to “Field-to-Wire Coupling in an Electrically Large Cavity: A Semianalytic Solution”

In this correspondence, we propose a supplementary spatial correlation function used to amend a simplification made in an earlier published paper in which a semianalytic solution of field-to-wire coupling in an electrically large cavity was first proposed. It can be shown that the horizontal and vertical components of the incident field are correlated in most cases. Without neglecting the correlation between the field components, the supplementary function can help to give more accurate results. It is demonstrated by two numerical simulation examples in which the semianalytic results are compared with the Monte Carlo results and/or the analytic solution.
