Simplified Cylindrical Electromagnetic Cloak for Reduction of RCS

In this paper، the performance and sensitivity of the cylindrical electromagnetic cloak considering the effect of different simplified cloaks are investigated. The performance of simplified cloak is less than ideal cloak; however، it can be realized in practice with acceptable level of RCS reduction. The exact wave solution for different regions of cylindrical cloak is derived and validated with full-wave simulations results based on COMSOL Multiphysics. Numerical experiments of RCS are performed for frequency band from 10MHz to 3GHz. The results of simulation show more than 18dB RCS reduction for simplified cloak.
