A low mass, fully cylindrical and dead region free GEM detector is under development as Inner Tracker for the KLOE experiment upgrade at the DAΦNE facility in Frascati. The proposed detector will play a crucial role in the study of the Ks decays and interferometry. The main physics requirements are: good detector spatial resolution σrφ about 200 μm and σz about 500 μm and a very low material bu...

A proper antenna to couple to a microstrip Microwave Kinetic Inductance Detector (MKID) is designed and simulated. A twin-slot microstrip-fed inline antenna is designed for frequency band of 600-720~GHz integrated with an elliptical lens and coupled to the MKID. A systematic design procedure for design of such antenna with microstrip inline feeding is presented. Whole structure of lens and twin...

background: a variable resolution x-ray (vrx) ct scanner provides a great increase in the spatial resolution. in vrx ct scanners, the spatial resolution of the system and its field of view (fov) can be changed according to the object size. one of the main factors that limit the spatial resolution of vrx ct scanner is the effect of the x-ray focal spot. materials and methods: a theoretical study...

In the mm-wave frequency band, rectifier’s sensitivity is bottleneck of a wireless-powered IoT transponder’s distance. At meter’s distance, received power weak, and transistors in front end wireless receiver operate weak inversion region. This article presents mathematical analysis multi-stage rectifier low-power A design methodology 57–64-GHz fully integrated eight-stage with bulk-drain connec...

This communication presents a freehand imaging system, which takes full advantage of compact multiple-input multiple-output (MIMO) radar to provide the real-time results by means movements. The system is based on commercial radar-on-chip, equipped with four receivers and two transmitters, an optical tracking (i.e., motion capture system) for retrieving its position attitude. reduced size enable...

Abstract We developed a novel terahertz-wave detector fabricated on SiC platform implementing an InP/InGaAs Fermi-level managed barrier (FMB) diode. The FMB diode epi-layers were transferred substrate, and waveguide coupler filters monolithically integrated with Then, the chip was assembled in fundamental mixer module WR-3 rectangular-waveguide-input port. It exhibited minimum noise equivalent ...
