We report a concentric cylindrical metamaterial (CCM) which can be used for acquiring a dark hollow light cone (DHLC). The proposed structure is composed of a concentric cylindrical silver–dielectric multilayer composite, which is covered by a thin layer of chromium (Cr) containing an annulus or a h...
