In this paper we present the results of analytical and numerical studies on the effect of change of permittivity of embedded defects on the transmission characteristics of epsilon-near-zero (ENZ) metamaterials. We investigated electromagnetic wave transmission in the microwave regime through an isot...

A compact analytical model of minority carrier -concentration is presented for an exponentially-doped quasi-neutral region of Silicon solar cell. It is an iteration-free and integral-free mathematical expression that addresses the non-uniformity in doping and contribution from terrestrial solar spec...
