Optical cages made of graphitic frameworks
J. P. Walker, H. Grebel
In pursuit of infrared (IR) radiation absorbers, we examine quasicrystal structures made of graphite wires. An array of graphitic cages and cage-within-cage, and whose overall dime…

Optical Cages
V. Kumar, J. P. Walker, H. Grebel
We examine array of metal-mesh frameworks for their wide-band absorption. These take the form of quasi-crystal optical cages. An array of cages tends to focus the incoming radiatio…
