A method to evaluate the Sommerfeld-Weyl-type integral rapidly in the far field is reviewed. With such a method, one can perform “back-of-the-envelope” derivations for the Far-Field expressions of Sommerfeld-Weyl-type integrals. First, the stationary phase point of the integrand is identified, which can be easily remembered from its physical interpretation. Next, we identify closed-form integrals that allow us to integrate the rapidly varying part of the integrand in closed form.
