Microwave localization due to defects in the arrays of dielectric cylinders: Multiple scattering approach

Microwaves propagation and scattering by dielectric cylinders in an uniform and defected media are simulated by using multiple scattering method. Formation of localized state due to the presence of a defect is observed in our simulations. Our theoretical results are compared with the previous experi...

Description
Summary:Microwaves propagation and scattering by dielectric cylinders in an uniform and defected media are simulated by using multiple scattering method. Formation of localized state due to the presence of a defect is observed in our simulations. Our theoretical results are compared with the previous experimental findings, yielding quantitative agreements in the transmission coefficients for a certain range of frequencies. In addition, our results point out some possible inconsistency in the experimental observations.
