“…When it comes to space applications, mass and volume of the instruments are also essential design considerations. Integration of antenna arrays coupled with detectors are ideal for such applications (Goldin et al 2002). In order to maintain optimum levels of sensitivity and resolution keeping in mind the importance of compactness, low mass focal plane antenna arrays provide an elegant alternative (Chattopadhyay 2010).…”

The terahertz (THz) band provides a transition between the electronic and the photonic regions thus adopting important characteristics from these regimes. These characteristics corresponding with the progress in semiconductor technology has enabled researchers to exploit hitherto unexplored domains including satellite communication, biomedical imaging, security systems, etc. This book, explores the terahertz antenna technology toward implementation of compact, consistent, and cheap terahertz sources, as well as the high-sensitivity terahertz detectors. The advances in new materials and nanostructures such as graphene will be helpful in miniaturization of antenna technology while simultaneously maintaining the desired output levels. Terahertz antenna characterization of bandwidth, impedance, polarization, etc. has not yet been methodically structured and it continues to be a major research challenge. This book addresses these issues besides including the advances of terahertz technology in space applications worldwide, along with possibilities of using this technology in deep space networks.

“…A pair of dual slot antennas oriented at 90 to each other will couple to two orthogonal polarizations which makes them a perfect choice for polarization measurements. Several research groups 10,11 are also developing designs to couple TES devices to polarization-sensitive planar antennas. We plan to fabricate the slot antennas on a Si wafer by patterning a Nb/SiO/Nb structure, where the groundplane and the microstrip transmission lines are separated by a layer of insulator (SiO).…”

We are developing a new type of detector for observational cosmology and astrophysical research. Incoming radiation from the sky is coupled to a superconducting microstrip transmission line that terminates in a thin film absorber. At sub-Kelvin temperature, the thermal isolation between the electrons and the lattice makes it possible for the electrons in the small absorber (100's of µm 3 ) and superconducting bilayer (Transition Edge Sensor) to heat up by the radiation absorbed by the electrons of the normal absorbing layer. We call this detector a Transition-edge Hot-electron Micro-bolometer (THM). THMs can be fabricated by photo lithography, so it is relatively easy to make matched detectors for a large focal plane array telescope. We report on the thermal properties of Mo/Au THMs with Bi/Au absorbers.

“…A highly desirable solution to the efficient wireless power transfer would be to fabricate monolithic array of antenna-coupled detectors on a planar substrate [4]. However, most planar antenna designs produce broad beam patterns, and therefore require substrate lenses or micro-machined horns for efficient coupling to the incoming beam [5].…”
