The Magic of Optics—An Overview of Recent Advanced Terahertz Diffractive Optical Elements
Diffractive optical elements are well known for being not only flat but also lightweight, and are characterised by low attenuation. In different spectral ranges, they provide better efficiency than commonly used refractive lenses. An overview of the recently invented terahertz optical structures bas...
