MIDAS : MoM Integral-equation Decomposition for Arbitrarily-shaped Scatterers

About this technology

Overview

MIDAS is a high performance MPI-parallelized FORTRAN implementation of a 3D full-wave model for electromagnetic (EM) scattering by arbitrarily-shaped and numerically large objects. The model is based on the use of a domain decomposition method known as the Characteristic Basis Function Method (CBFM) in a context of VIEM/MoM (Volume Integral Equation method / Method of Moments).The main goal is to efficiently calculate multi-static full-wave EM scattering by arbitrarily shaped large objects. MIDAS is currently applied to two scattering problems :1) Calculation of single scattering properties (SSPs) of precipitation particles at microwave frequencies, which is useful for the NASA precipitation measurement missions (PMM) and Aerosols Cloud Convection and Precipitation (ACCP) projects.2) calculation of multi-static 3D EM scattering by realistic models of asteroids/comets at HF frequencies (5-20 MHz), which supports ongoing small satellites sounding efforts, for space science.
