In this paper, we focus on PHYTOPOROUS, a porous carbon material made entirely from plant-based ingredients, as a new broadband-wave absorber material that acts in the millimeter wave band. We created prototypes of thin rubber-sheet wave absorbers th

In recent years, there has been increased interest in the terahertz waveband for application to ultra-high-speed wireless communications and remote sensing systems. However, atmospheric propagation at these wavelengths has a significant effect on the

Rain attenuation at 355.2 GHz in the terahertz wave range was measured with our new 355.2 GHz measuring system under rainfall intensities up to 25 mm/hr. Rain attenuation coefficients were also calculated using four raindrop-size distributions, e Mar

Targeting the transition from a coaxial wave guide to a coplanar wave guide (CPW), a microwave and millimeter-wave wide-band coaxial-to-coplanar transition is proposed. This design connects the coaxial inner conductor to the CPW center conductor in a

The fundamental dielectric properties of nematic liquid crystals were measured in the 3–33 GHz frequency range for the purpose of applying liquid crystals to adaptive devices in the microwave and millimeter-wave ranges. We proposed two kinds of mea

The dielectric constant of liquid crystals at microwave and millimeter-wave frequencies is measured directly with an inductively coupled ring resonator of a microstrip line configuration, which is widely used for the development of many adaptive devi
