Although respiratory sounds are useful indicators for evaluating abnormalities of the upper airway and lungs, the accuracy of their evaluation may be limited. The continuous evaluation and visualization of respiratory sounds has so far been impossibl

We demonstrate the highly sensitive terahertz (THz) sensing of a water-glycerol mixture poured on a metamaterial surface using reflection-based THz time domain spectroscopy. The reflectance at the resonant dip frequency changes significantly with gly
We studied the transmission characteristics of a planar metamaterial consisting of an array of electric split-ring resonators (eSRRs) with double periodicity. Because of coupling between different resonant modes induced by different lattice periods i

2015 40th International Conference on Infrared, Millimeter, and Terahertz waves (IRMMW-THz).
A terahertz wave absorber composed of dielectric spheres is proposed. The proposed absorber offers advantages compared to other metamaterial-based absorbers owing to low-cost and flexibility of fabrication that strongly relaxes the constraints for th

We experimentally demonstrate control over the group delay of narrow-band (quasi continuous wave) terahertz (THz) pulses with constant amplitude based on optical switching of a metasurface characteristic. The near-field coupling between resonant mode

Spectral and polarization characteristics of terahertz waves radiated from metaatom-loaded photoconductive antennas strongly depend on shape, direction, and position of metaatoms. These characteristics are interpreted based on the symmetry and induce

Quasi-monodisperse dielectric particles organized in a periodic hexagonal network on an aluminum surface are exploited numerically and experimentally as a single-layered near-perfect absorber in the terahertz regime. Of particular interest are titani

Optical switching of the spectrum and polarization of terahertz radiation from split-ring resonator-loaded photoconductive antennas has been demonstrated. The switching is based on the sensitivity of the resonance of a split-ring resonator on a photo
