TL;DR: In this article, a good general agreement is obtained for curves of beamwidth versus length, normalized to wavelength, when one compares the data with that for traveling-wave antennas published by Zucker.

TL;DR: Tapered slot antennas (TSAs) with a number of potential applications as single elements and focal plane arrays are discussed in this paper, where the circuit and radiation properties of TSAs are reviewed.

TL;DR: In this paper, a detailed phenomenological theory for the determination of conversion properties is presented, which is capable of predicting the frequency-conversion loss rather accurately for arbitrary bias by examining the I-V characteristic, Knowing the electron temperature relaxation time, and using parameters derived from the I -V-characteristic also allows to predict the -3-dB IF bandwidth.

TL;DR: In this article, the authors measured the noise temperature of a single, sensitive superconducting NbN hot electron bolometer (HEB) mixer in a frequency range from 1.6 to 5.3 THz, using a setup with all the key components in vacuum.

TL;DR: In this article, it was reported that terahertz radiation from 069to254THz has been sensitively detected in a device consisting of bundles of carbon nanotubes containing single wall metallic carbon nanite tubes, quasi-optically coupled through a lithographically fabricated antenna, and a silicon lens.
