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 hole opening for incidence. The simulation results show that nanometer-level dark hollow light cones with good quality can be formed in the output for circularly polarized incidence and its position can be monitored by choosing different dielectric materials and dimensions of annular apertures. Such a dark hollow light cone is believed to have potential applications in manipulating atoms and molecules.||URI:||https://hdl.handle.net/10356/99268
