Cellular ceramic substrates are extensively used for pollution control systems in vehicles. The manufacturing process of them can involve microwave drying. In this study, we describe the development of a modeling framework for the microwave drying process of these substrates. The ... En savoir plus

For more than thirty years the GeePs Laboratory has been working on the numerical simulation of electromagnetic systems through numerous research topics. During this conference, we propose to present a recent problem that has been addressed by the laboratory. This application concerns ... En savoir plus

In this paper will be presented how an electronic system and its components will respond in case of an impact of an external electromagnetic pulse (EMP). In the first instance the coupling process of transient electromagnetic pulses into electronic systems will be shown. Out of that the ... 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

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

Illegal immigrants and smugglers frequently use underground tunnels to avoid border security and checkpoints. In addition, the threat of international terrorism has recently made the effort to detect tunnels a national security priority. No single technology and sensing modality is ... En savoir plus

Many industrial processes involving chemical reactions rely on heat addition, which accounts for approximately 50% of all energy consumed in the United States' industrial sector. Examples include metallurgical processes, chemical processing, and heating process fluids. Traditionally, ... En savoir plus

The measurement of dielectric constant at frequencies of 20 GHz or greater is important for specifying the optical properties of materials at millimeter wavelength. One method of measurement uses a resonant cavity containing a sample of the material, and relates the resonant frequency ... En savoir plus

The paper on EMC Simulation Analysis of Enclosures demonstrates a simulation method to analyze the shielding effectiveness of enclosures. From the early development stage on it is possible to analyze the effect of electromagnetic waves on shielding panels. Different types of openings ... En savoir plus
