Abstract: This detection device is provided with a transmission unit that generates electromagnetic waves, a compartment bottom portion by which electromagnetic waves are reflected, and a reception unit that receives electromagnetic waves. The transmission unit emits electromagnetic waves to a detection target region through a partition member for partitioning the detection target region from the transmission unit and the reception unit. The compartment bottom portion is provided on the optical path of the electromagnetic waves emitted from the transmission unit and reflects electromagnetic waves having passed through at least a portion of the detection target region. The reception unit receives electromagnetic waves that have been reflected by the compartment bottom portion and are inputted from the detection target region through the partition member.

Abstract: A terahertz device of the present invention includes a terahertz element generating an electromagnetic wave, a dielectric including a dielectric material and surrounding the terahertz element, a gas space including a gas, and a reflecting film serving as a reflecting portion. The reflecting film includes a portion opposing the terahertz element through the dielectric and the gas space and reflecting the electromagnetic wave toward a direction, wherein the electromagnetic wave is generated from the terahertz element and transmitted through the dielectric and the gas space. In addition, the refractive index of the dielectric is lower than the refractive index of the terahertz element and is higher than the refractive index of the gas in the gas space.

Abstract: The THz device module includes: a substrate; a THz device disposed on a front side surface of the substrate, and configured to oscillate or detect THz waves; a cap covering the THz device being separated from the THz device, and comprising an opening formed at a position opposite to the THz device in a vertical direction of the front side surface of the substrate; and a sealing member covering the opening of the cap so as to seal the THz device in conjunction with the substrate and the cap. A distance from the THz device to the sealing member is within a near-field pattern to which an electric field of the THz waves can be reached without interruption from a surface of the THz device to the sealing member. The THz device module efficiently emits or detects THz waves from the opening, thereby suppressing upsizing of the cap.
