Abstract
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. Closed-form integrals are then identified that can be used to integrate the rapidly varying part of the integrand in closed form
