The analysis of high-frequency scattering from electrically large open-ended ca¨ities is addressed in this work. The magnetic field ( ) integral equation MFIE is obtained for the equi¨alent currents on the interior ca¨ity walls and is sol¨ed in a single iteration by using a new ( ) progressi¨e physi
The analysis of radiation and scattering from a multiregion ( ) quasiplanar structure using the con¨entional method of moments MoM is computationally expensi¨e. To circum¨ent this difficulty, a computational scheme that supplements the classical MoM with the steepest descent fast-multipole algorithm
An FFT-based formulation for the computation of electromagnetic scattering from 3-D, perfectly conducting objects is presented. The formulation solves the EFIE iteratively via a conjugate gradient scheme and has the major advantage of a low storage requirement for scatterers in the resonance region.
## Abstract The forward–backward method with a novel spectral acceleration algorithm (FB/NSA) has been shown to be a very efficient 𝒪(__N__~tot~) iterative method of moments, where __N__~tot~ is the total number of unknowns to be solved, for the computation of electromagnetic wave scattering from t
