Perfect Broadband Terahertz Antireflection by Deep‐Subwavelength, Thin, Lamellar Metallic Gratings
Source abstract
Abstract
Perfect broadband terahertz antireflection coatings are demonstrated by deep-subwavelength, thin, lamellar metallic gratings both in theory and experiment. Abrupt phase changes introduced by grating to terahertz wave traversing the coated surface can be tuned from 0 to π as a function of grating parameters. At π/2, the impedance difference between two dielectrics is matched and perfect antireflection occurs.
