AMPERE conference about Microwave and HF heating

The 13th International Conference on Microwave and High Frequency Heating on behalf of the Ampere Association (AMPERE Conference) was held from 5 to 8 September 2011 at the “Ecole National Supérieure d’Electrotechnique, d’Electronique, d’Informatique, d’Hydraulique et des Télécommunications de Toulouse” (ENSEEIHT), France.

The conference, held every 2 years, was an excellent occasion for academic researchers and engineers from industries to show the latest achievements, to exchange innovative ideas of research, and to promote the most recent advanced investigations in the applications of microwave and high frequency technologies at laboratory and industrial level.

Researchers of the Microwave Division (DIMAS) participated in the organization of the conference, in the technical program and in the exhibition section. The following picture shows some DIMAS researchers in the exhibition room with some of the recent developments in the field of microwave measurements (portable impedance measurement system, high power impedance measurement system and dielectric kit for vials).

In the technical program, DIMAS participated with contributions in the oral sessions and poster sessions with the following papers:

Short course about microwave and HF heating basics

As part of the 13th International Conference on Microwave and High Frequency Heating on behalf of the Ampere Association held in Toulouse (France), a special one-day short course on microwave processing technologies was offered on Monday September 5th, 2011.

The short course covered the basics of microwave and high frequency heating, with special focus on the fundamentals of microwave heating, operation, dielectric properties, design and modelling of microwave devices and an overview of industrial microwave applications.

Course participants came from industry and research, as well as graduate students with diverse interest in applied microwave technologies and applications.

The lectures were provided by a group of international experts from the academia and the industry in the fields of industrial microwave processing, measurements, materials, microwave devices, modelling and computational methods.

The program of the short course was the following:

Seminar about determining material parameters

The 13th Seminar “Computer Modeling in Microwave Engineering and Applications: Advances in Determining Material Parameters” was held in Thun, Switzerland, at the Swiss Federal Laboratories for Materials Science and Technology (EMPA) last March 7-8, 2011.

The Seminar was organized by IMMG of the Department of Mathematical Science, WPI and the Laboratory for Advanced Material Processing (EMPA) and endorsed by AMPERE (Association for Microwave Power in Europe for Research and Education).

This one-and-a-half day interdisciplinary forum was focused this year in the determination of microwave parameters as dielectric properties. Electromagnetic and thermal parameters of materials are of high importance to the designers of systems for microwave thermal processing. Determination of these parameters is experimentally challenging and, at the same time, involves (usually quite non-trivial) computation of the parameters in question from measurable quantities.

The attendees shared their experience in the related fields with their counterparts, discussing major issues that slow down development of adequate and accurate technologies for measurement of dielectric properties of materials at microwave frequencies.

Members of DIMAS participated in the Seminar with two talks:

J. M. Catalá-Civera and F.L. Peñaranda-Foix, “An Overview of Dielectric Properties Measuring Techniques and Instruments”, Proc. 13th Seminar “Computer Modeling in Microwave Engineering and Applications – Advances in Determining Material Parameters” (Thun, Switzerland, March 2010),

J.M. Catalá-Civera, F.L. Peñaranda-Foix, J.D. Gutierrez, P.J. Plaza-González, and A.J. Canós-Marín, “Robust, Compact, Reliable and Portable Dielectric Properties Measurement System for Powder Materials at Microwave Frequencies”, Proc. 13th Seminar “Computer Modeling in Microwave Engineering and Applications – Advances in Determining Material Parameters” (Thun, Switzerland, March 2010),
