Abstract :
Evaluating Sommerfeld integrals used to be a standard nightmare for many electromagnetic engineers due to the singular, oscillating and divergent behaviour of their integrands. The goal of this paper is to show a FORTRAN library for computing this kind of integrals and the related numerical details. Using this library, the user can compute twelve integrals of this kind. All the integrals can be evaluated using two different methods; direct numerical integration and asymptotic evaluation.
