Double-layered dielectric wedges (e.g. forest or snow-covered hills, building corners with vertical gardens) are quite common obstacles that appear in radio-wave propagation channels. This article presents a heuristic method to obtain the field diffracted from a double-layered dielectric wedge. Though it uses a framework that appeared in an earlier publication, it improves upon the issue of complexity. The method proposed here reduces the requirement of solving nonlinear equations to half and makes the process substantially less time-consuming without compromising the accuracy. Hence this improvement makes the method more useful for real-time usage in emergency situations. Apart from this advantage on time consumption, this method also improves upon the memory consumption and limit of validity.
