Prior information about the average dielectric properties of breast tissue can be implemented in microwave breast imaging techniques to improve the results. Rapidly providing this information relies on acquiring a limited number of measurements and p

In this letter, we report the near quantum-limited performance of a 230 GHz endfire superconductor-insulator-superconductor (SIS) mixer utilizing a Nb/Al-AlOx/Nb trilayer. An important feature of this mixer is its use of a unilateral finline for the

Electromagnetic waveguides have dispersive properties, meaning the phase and group velocities change with frequency. This dispersion leads to broadening in the time-domain impulse response, which can make it difficult to separate adjacent signals if

We describe the performance of a superconductor–insulator–superconductor (SIS) mixer operating in the frequency range of 780–950 GHz. Unlike most SIS mixers, the tunnel junction employs two different superconductors, a niobium nitride top and a

Adrenal tumors are very commonly encountered in the practice of radiology. They may arise from the adrenal gland itself, either the cortex or the medulla, or they could be secondary lesions. They may be benign or malignant. The functioning adrenal tu

We present a new concept for constructing a compact linear 1 × $n$ multi-beam phased array transceiver system that can be scaled to operate from radio to millimetre wavelength. In this design, all the components required to form the phased array are
