MICROWAVE EVALUATION OF EFFECTIVE ELECTROMAGNETIC PROPERTIES OF METAL-DIELECTRIC METAMATERIAL WITH SPHERICAL INCLUSIONS
摘要
An analytical modeling and numerical analysis of the effective electromagnetic response of two- component metamaterial medium with spherical metallic inclusions is presented. Calculations have been made within the microwave frequency range. The analytical modeling has been done using two different modified mathematical models of the complex relative permittivity and permeability for unbounded composite medium with spherical inclusions. Numerical simulations of the above mentioned parameters have been made using S-parameters obtained from Finite-Difference Time-Domain technique. The numerical simulation has been carried out for different radii of the inclusions. Remarkable coincidence between analytical and numerical results was found. The enhancement of effective relative permittivity and refractive index of the considered composite has been observed. Recommendations for the practical application of presented artificial material for designing microwave patch antennas have shortly been discussed.
