In this article, we provide an overview of various numerical methods used in Computational Electromagnetics (CEM), with a special focus on antenna simulation methods such as FDTD, FEM, MoM, CMoM, FMM, MLFMM, FVTD, GO, GTD, UTD, PO, PTD, and DDM.

AN-SOF introduces an innovative method based on James R. Wait theory to accurately compute ground losses, improving monopole antenna design. Explore the validated model for LF/MF radio masts.

Introducing AN-SOF’s Conformal Method of Moments, an advanced approach to wire antenna design. By overcoming several limitations of traditional techniques, this method enables accurate modeling and analysis of antennas with complex geometries.

Two-wire transmission lines can be modeled explicitly in AN-SOF. In this example, the line will have a single wire but there will be a ground plane below it, so we have the mirror image of the wire as the return of the line.

The ability of AN-SOF to simulate at extremely low frequencies can be demonstrated with a model of an RLC circuit that will resonate at only 800 Hz, so the wavelength is 375 km!
