OPTISCHES BAUELEMENT ZUR FREQUENZSELEKTIVEN REFLEXION IM GIGAHERTZ- UND TERAHERTZ-BEREICH |
摘要 |
An optical component for effecting frequency selective reflection in the gigahertz and terahertz frequency ranges and for effecting wave permeability includes at least one first layer ( 1, 3, 5 ) made of a first material (m 1 ). The first material is optically permeable to electromagnetic radiation of a reference frequency (f) between 5 gigahertz (GHz) and 10 terahertz (THz) and has a first refractive index (n 1 ) and an optical thickness of approximately one-fourth the wavelength (lambda) of the electromagnetic radiation of the reference frequency (f) in the first material (m 1 ). There is at least one second layer ( 2 ) situated underneath the first layer ( 1 ) that is made of a second material (m 2 ) which is optically permeable to electromagnetic radiation of a reference frequency (f) and which has a second refractive index (n 2 ) and an optical thickness of approximately one-fourth or one-half the wavelength (lambda) of the electromagnetic radiation of the reference frequency (f) in the second material ( 2 ), thus the first refractive index (n 1 ) and the second refractive index (n 2 ) are different. |
