“…Such films show lower density than that of the bulk form, and have several potential applications in catalytic surfaces [1,2], micro-sensor elements [3][4][5], low dielectric materials [6], etc. The theories of the electromagnetic wave propagation in STF have been well established [7][8][9][10]. With the help of state of the art technology, the nanostructure of the GLAD films can be fabricated in different forms, from the simple microstructures, i.e., oblique column, zigzag, helix [11][12][13], to exotic nanostructures, i.e., polygonal spirals, superhelices, etc.…”
