From: A novel EM concentrator with open-concentrator region based on multi-folded transformation optics
Simulation results of open-coating concentrator under different incident waves. (a) Electric field (\({E}_{z}\)) distributions for the proposed concentrator under the illuminations of plane waves with incident angles of 0° and same incident waves are applied in (b) for the open-coating concentrator. (c) The incident angle of propagating waves are changed to 90° for (b). In all cases, the functionality of proposed concentrator is equivalent to previously designed TO-based concentrators21. (d) The EM waves of point source is concentrated in (e) closed concentrator and (f) open-concentrator. Similarly, emission of linear source in (g) is concentrated in (h) closed concentrator and (i) open-concentrator. In all cases, the results give the immediate validation of the proposed open-concentrator device.
