We would like to thank Dr. Guangran Zhu for pulling together our first website and for providing the very nice simulation below. It shows a plane wave hitting upon 6 dielectric cylinders that spells out COMPEM, which stands for computational electromagnetics. The incident pulse is Gaussian-modulated at 1 GHz with unit amplitude. The dielectric cylinders are about 4 wave length in width and height and have relative permittivity of 4. The total-field scatter-field boundary uses the analytic field propagator formulation and the absorbing boundary uses the uniaxial perfectly matched layer formulation. The animation is on log scale to magnify the trapped waves inside the cylinders.
