Nonsingular and thin cloak using linear transformation function

Abstract

This paper presents non singular and thin cylindrical electromagnetic cloaks which are designed by coordinate transformation based on linear function. The derived material parameters are free of any infinities and singularities at the inner boundary of cloak which is good for its realization. The effects of parameters `s' and `b=a' ratio have been discussed on the performance of cloak. All the designs have been validated by simulation results.
