Recently published theory has suggested that a cloak of invisibility is in principle possible, at least over a narrow frequency band. We present here the simulated realization of such a cloak. The cloak can construct using artificially structured metamaterials designed for operation ... En savoir plus

Electromagnetic (EM) flowmeters are important flow sensing devices across industries like oil and gas and power generation. The EM flowmeter works on the principle of Faraday’s law of electromagnetic induction. In short, when an ionic fluid like water flows through a pipe, in the ... En savoir plus

Cylindrical single or multi-turns coils and Spiral Flat multi turn coils are used in pulsed magnetic technologies for which both magneto-harmonic and transient magnetic analysis are required. The first are mainly used for tubular geometries and the second are preferred for sufficiently ... En savoir plus

In the humanitarian demining setting, it is crucial to detect landmines with reliable sensing performance. As Nuclear Quadrupole Resonance (NQR) is an effective method for detecting explosive materials, our group is currently developing the world’s first low-cost system for anti-vehicle ...

This report addresses design of a PCB intended for use as a busbar integrated with multiple DC-link (rail) capacitors in a high power inverter. The geometry and current ratings are typical of a 50 kW unit operating at 60kHz in an intermittent mode. First, circuit aspects are analyzed. ... En savoir plus

Every year, in the United States alone, more than 40,000 infants are born with congenital heart defects (CHD) and an additional 550,000 adults are diagnosed with heart failure. Every year, $110 billion is spent on treating heart attacks and $20-39 billion on heart failure in the US. The ... En savoir plus

In electric distribution network, current and voltage measurement for metering, monitoring, and protection & control applications is done via instrument transformers (current and voltage transformers). These measurement devices are deployed during the construction phase of the ... En savoir plus

Electromagnetic fields are pervasive in today’s urban environment and under certain circumstances exposure has led to safety hazards that have been reported to cause personal injury. The United States Department of Labor has reported multiple cases of electrical shock on construction ... En savoir plus

Introduction: Wireless power transfer (WPT) is an emerging technology for charging implantable devices, industrial devices, and consumer electronics. It can be categorized as short-distance, mid-range, and long-distance WPT based on the distance between the transmitter (Tx) and the ... En savoir plus

As a high-tech silicon producer, it is our goal to provide efficient and sustainable production technologies. This requires to constantly upgrade our production concept. Thus, material and design innovations are an inevitable part of our everyday work, which leads our microwave ... En savoir plus
