Complex-Source-Point Narrow-Waisted Ray-Like Gaussian Beams for frequency and Time Domain Radiation and Scattering

Conclusions

In many current forward and inverse scattering scenarios, there is a need for numerically efficient robust forward solvers for fields excited by distributed sources in the presence of complex environments. This motivation has led us to re-visit the previously developed FD narrow-waisted Gaussian beam algorithms (Maciel and Felsen, 1989; 1990a,b) and to extend them to new FD applications as well as to the short-pulse TD. The outcomes from the rough sinusoidal scattering example here, as well as the first results in the TD, are encouraging. Further FD extensions to irregularly rough interfaces between dielectrics are already in progress, as are TD interactions with canonical scatterers to learn the new rules.
