Post processing is the last of the five primary steps of simulation development. This step represents the payoff from all the hard work of the previous steps, and it drives the deeper understanding of the design that engineers obtain though simulation. A simulation engineer can significantly improve their understanding, and better communicate that understanding, when […]

Many simulations are quasi-static, or steady state, because the results are independent of time. Time dependent simulations introduce additional challenges over time independent cases. The data generated during a time dependent simulation could be many gigabytes. Thus, the simulation engineer needs to balance the volume of output data with their needs for data at critical

Frequency domain simulation techniques are widely used to analyze the behavior of arbitrarily shaped objects and complex materials. One of the disadvantages of traditional frequency domain techniques, however, is the computational cost involved in obtaining solutions over a range of frequencies. Simulations have to be repeated at each frequency of interest to obtain a complete

Computational Analysis of Scattering of Electromagnetic Waves by Particles A computational model of Mie scattering was developed using COMSOL Multiphysics® and its RF Module. It solves for the scattering off a dielectric, magnetic or metal spherical particle with radius a. The model geometry is shown in Figure 1. The air domain is

Scattering of Electromagnetic Waves by Particles Interaction between electromagnetic waves and particles produce unique scattering patterns that are wavelength and particle size dependent. As electromagnetic waves propagate through matter they interact with particles or inhomogeneities and locally perturb the local electron distribution. This variation produces periodic charge separation within the particle causing oscillation
