Abstract
Here, we theoretically suggest the possibility of optical cloaking by employing the binary optimization of plasmonic nano-bi-dome. The proposed cloaking mechanism is based on reducing the total scattering coefficient in optical frequency. Since the scattering coefficient depends strongly on the number of plasmonic nano-particles and the nano particles location, binary particle swarm optimization (BPSO) algorithm is proposed to design an optimized array of the plasmonic nano-bi-domes in order to achieve the minimum scattering coefficient in the optical frequency. In BPSO, a swarm consists of a matrix with binary entries, control the presence (‘1’) or the absence (‘0’) of nano bi-domes in the array.
