The magnetrons used in microwave ovens operate on the same frequency band as Wi-Fi equipment, and the radiation they release can interfere with the operation of wireless networks. This paper presents a multiphysics simulation of a magnetron using CST STUDIO SUITE®, with the aim of testing the electrical, magnetic, thermal and mechanical characteristics of a low-interference magnetron design. Th...

This paper introduces an interferometric technique for the phase measurement of microwave devices. A handheld vector network analyzer (VNA) is presented for HF and VHF applications. A wideband synthesizer with multiple synchronized outputs is developed for extending the frequency range to the microwave band. The phase differences between the output signals can be set digitally with sub-degree a...

In this communication, a preliminary analysis of the solution of microwave imaging problems for ground penetrating radar applications has been proposed. Such a task has been fulfilled by exploiting the theory of compressive sensing in a linearized multiview-multistatic single-frequency framework.

This paper presents the Volterra input-output map as an extension of the S-parameters towards weakly nonlinear RF and microwave devices. This ‘VIOMAP’ can be measured and it can be used to predict the behavior of cascaded nonlinear twoports.

In order to understand the possible processes of charge transport common to ferroelectric ceramics and high Tc superconductors a variety of investigations aie underway. Microwave studies on these materials have attracted the attention of scientists in recent years. Some potential experimental techniques for studying ferroelectrics and superconductors will be discussed. Some common intrinsic fea...

A highly sensitive weak current detection circuit for implantable glucose monitoring is presented. The circuit consists of a current splitter, an integrator, a sampling/holding (S/H) circuit, and an 8-bit successive approximation register (SAR) analog-to-digital convertor (ADC). T-switches, source voltage shifting and correlated double sampling (CDS) technology are adopted to reduce the effects...
