Abstract
A system and a method for a nanostructured film including a first layer for reflecting at least a portion of an electromagnetic radiation and a second layer for receiving the remainder of the electromagnetic radiation through the first layer and subsequently reflecting at least a portion of the received electromagnetic radiation through the first layer, wherein two electromagnetic radiations with the same wavelength reflected by the first and second layers respectively are combined to form a strengthened electromagnetic radiation, the wavelength of the strengthened electromagnetic radiation being variable based on the physical property of the first layer.
Claims23
A nanostructured film, comprising
- a first layer for reflecting at least a portion of an electromagnetic radiation;
- and
- a second layer for receiving the remainder of the electromagnetic radiation through the first layer and subsequently reflecting at least a portion of the received electromagnetic radiation through the first layer;
- wherein two electromagnetic radiations with the same wavelength reflected by the first and second layers respectively are combined to form a strengthened electromagnetic radiation, the wavelength of the strengthened electromagnetic radiation being variable based on a physical property of the first layer, and wherein:
- (a) the first layer is dual-phase or (b) the second layer is an amorphous metallic layer or (c) both the first layer is a dual-phase and the second layer is an amorphous metallic layer.
