Efficient integral equation solution of electromagnetic scattering by arbitrarily shaped objects in planar, multilayered media
… formulations, this is due to the presence of the Sommerfeld integrals required for obtaining the Green's functions in spatial form.

A STUDY FOR THE PROPAGATION OF ELECTROMAGNETIC WAVES OVER IMPERFECT GROUND PLANES BASED ON SCHELKUNOFF INTEGRALS
… for the analysis of this problem uses the Sommerfeld formulation. In Sommerfeld formulation, the wave function corresponding to a point source is expanded in terms of the propagation constants of the various waves in the radial direction from the source. This gives rise to the well-known …

A study on computational electromagnetics problems with applications to casimir force calculations
… DGLM requires the evaluation of semi-infinite Sommerfeld integrals which prove to be a costly venture. An interpolation scheme is proposed here to allow for more efficient calculations of the Sommerfeld integrals. The interpolation is unique by its reuse of the same interpolation matrix to …

Computational electromagnetics for microstrip and MEMS structures
… which is represented in terms of only two Sommerfeld integrals and is suitable for developing fast algorithms. The path deformation technique and the multipole-based acceleration are used to expedite the matrix-vector multiplication. Both the computation time per iteration and the memory …

A Characteristic Mode Analysis of Conductive Nanowires and Microwires Above a Lossy Dielectric Half-Space
… a modified Green’s function using the rigorous Sommerfeld integrals. Our results show that the relative permittivity of the substrate decreases the resonance frequencies of the nanowires and significantly alters their radiation patterns. Most importantly, we find that, if the nanowire is near …

Characteristic Mode Analysis of Crumpled Graphene Flakes and A New Green’s Functions Evaluation Method for Layered Media
… method, which replaces the tail region of Sommerfeld integrals with its equivalent closed form expressions. Further, a detailed study on the types of contours has been carried out to understand their merits and demerits. Finally, the best available contour method has been identified in …
