Effective-medium-cladded dielectric waveguides for terahertz communications
Weijie Gao, Xiongbin Yu, Masayuki Fujita +3
Terahertz communications is a promising modality for future short-range point-to point wireless data transmission at rates up to terabit per second. A milestone towards this goal i…
Reflectarray antennas for terahertz communications
Tiaoming Niu, Withawat Withayachumnankul, Benjamin S. -Y. Ung +4
Reflectarrays composed of resonant microstrip gold patches on a dielectric substrate are demonstrated for operation at terahertz frequencies. Based on the relation between the patc…
Sub-diffraction thin-film sensing with planar terahertz metamaterials
Withawat Withayachumnankul, Hungyen Lin, Kazunori Serita +6
Planar metamaterials have been recently proposed for thin dielectric film sensing in the terahertz frequency range. Although the thickness of the dielectric film can be very small…
Effects of mutual coupling in dual-resonance metamaterials
Withawat Withayachumnankul, Christophe Fumeaux, Derek Abbott
This Letter presents an investigation on the effects of mutual coupling in a metamaterial comprising two sets of electric-LC (ELC) resonators with different resonance frequencies.…
Compact electric-LC resonators for metamaterials
Withawat Withayachumnankul, Christophe Fumeaux, Derek Abbott
Alternative designs to an electric-LC (ELC) resonator, which is a type of metamaterial inclusion, are presented in this article. Fitting the resonator with an interdigital capacito…
