Asymmetric planar terahertz metamaterials
Optics Express, 2010 We report an experimental observation of three distinct resonances in split ring resonators (SRRs) for both vertical and horizontal electric field polarizations at normal incidence by use of terahertz time domain spectroscopy.

Terahertz metamaterials and systems based on rolled-up 3D elements: designs, technological approaches, and properties [PDF]
Scientific Reports, 2017 Electromagnetic metamaterials opened the way to extraordinary manipulation of radiation. Terahertz (THz) and optical metamaterials are usually fabricated by traditional planar-patterning approaches, while the majority of practical applications require ...

Active terahertz metamaterial devices [PDF]
Nature, 2006 The development of artificially structured electromagnetic materials, termed metamaterials, has led to the realization of phenomena that cannot be obtained with natural materials. This is especially important for the technologically relevant terahertz (1 THz = 10(12) Hz) frequency regime; many materials inherently do not respond to THz radiation, and ...
