Low-cost antireflection coatings for terahertz light employing multilayered polymer films and adhesives

Antireflection coatings (ARCs) provide a powerful method to reduce reflective losses and eliminate spurious reflections that can limit experiments. At Terahertz (THz) frequencies, ARC options remain limited. To address this, we employ a combination of commercially available polymer adhesive tapes and films to create ARCs for THz light, that can be applied on a wide range of substrates. In addition...
