Auto-adaptive algorithm using frequency derivatives of harmonic equations for automatic search of resonances

Description

Electromagnetic modeling provides high accuracy but is often too time-consuming. Solving electromagnetic scattering and radiation problems with moment methods or finite element methods over a large frequency band requires the computer code to be run for every frequency sample. This is too expensive. So we propose a fast, accurate methodology for calculating the electromagnetic behaviour of an antenna with very few simulations over a large frequency band.
