This paper presents the concept of a lens-integrated CMOS camera-type terahertz (THz) compact antenna test range (CATR) to determine the far-field characteristics of transmitters (TX), including the radiation pattern, directivity, half-power beamwidt

Light-field (LF) refers to the spatio-directional light flow in space. In LF imaging, light rays are recorded along different positions and directions, and a 3-D scene is reconstructed with back-propagation [1]. Modern visible-light LF cameras assemb

Oxygen depleted semiconducting Y-Ba-Cu-O exhibits an amorphous phase ( $a$ -YBCO), obtained at low deposition temperature (150 °C), which can be applied to fast uncooled near-infrared or THz detection. In the first part, we investigate room temperat

Decoupling the desired spectral signal from scattering events and also from the sporadic signals from the background has been a challenge for fulfilling the promise of real-time applications exhibited by the present broadband terahertz devices. Perfo

This paper presents a CMOS camera-type THz compact antenna test range (CATR) to facilitate a convenient means to measure far-field radiation patterns of transmitters (TXs). For concept validation, we measured the far-field radiation pattern of a 26-d

Hot electron bolometers (HEB) exploiting the properties of the high-TC superconductor (HTS) Y-Ba-Cu-O, are offering a competitive alternative to THz Schottky mixers, which require moderate cooling (e.g., 60 to 80 K). This arises from the HTS HEBs exp

The well known Y-Ba-Cu-O superconductor (oxygen rich) material also exhibits a semiconducting phase (oxygen depleted), which offers in its amorphous form (a-YBCO), an attractive solution for the easy fabrication of room temperature thermal radiation

In this paper, a silicon lens-integrated CMOS THz camera is employed as a compact antenna test range. The far-field radiation pattern of a 26-dBi 0.852-THz standard gain horn antenna radiation source is characterized. Both single-frame low-resolution

Since the observation of pyroelectric properties in oxygen depleted semiconducting Y-Ba-Cu-O, the interest of its amorphous phase (a-YBCO) obtained at low deposition temperature (150 °C) has been demonstrated for near-infrared (NIR) detection. At th
