Abstract. Here, we describe a technique to define the Singularity
Expansion Method (SEM) poles for short-circuited thin-wire structures
developed using the Method of Modal Parameters (MoMP). The MoMP method
consists of in the expansion of the system of mixed-potential integral
equations (MPIE) into the Fourier series, including the kernels containing
Green's function. Corresponding equations for Fourier modes contain infinite
matrices of p.u.l. inductance and capacitance, and the solution for current
can be obtained using the infinity matrix of p.u.l. impedance. The SEM poles
are given by the zeros of the determinant of this matrix. For the case of
the symmetrical circular loop, this equation transforms to one well-know
from the literature. Numerical investigation of solutions for the poles of
the first layer has shown good agreement with previously obtained analytical
and numerical results for different wire configurations.
