Abstract :
A deterministic method is proposed for the computation of zeros within a complex plane by using Cauchy´s theorem. The integrals have been calculated for different numbers of integration points by the Gaussian integration formula. As an example, several eigenmodes of a TE/TM mode splitter have been determined by the proposed method
