Manifestation of the coupling phase in microwave cavity magnonics
Alan Gardin, Jeremy Bourhill, Vincent Vlaminck +4
The interaction between microwave photons and magnons is well understood and originates from the Zeeman coupling between spins and a magnetic field. Interestingly, the magnon/photo…
Super Low Resolution RF Powered Accelerometers for Alerting on Hospitalized Patient Bed Exits
Michael Chesser, Asangi Jayatilaka, Renuka Visvanathan +3
Falls have serious consequences and are prevalent in acute hospitals and nursing homes caring for older people. Most falls occur in bedrooms and near the bed. Technological interve…
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…
Ultra-high and Tunable Sensitivity Leaky-Wave Scanning Using Gain-Loss C-section Phasers
Nghia Nguyen-Trong, Lianfeng Zou, Christophe Fumeaux +1
A periodic leaky-wave antenna (LWA) with tuning capability and enhanced scanning sensitivity is introduced in this paper. This antenna leverages the concept of active Gain-Loss C-s…
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…
