Research activities

Det blir gitt prosjekt- og hovedoppgaver innen dette emnet og tilstøtende problemer innen emnet (f.eks EMC, effektiv skjerming av magnetfelter, curie-temperaturens regulerende egenskaper ved ståloppvarming). Forskningsfeltet startet 1995 og flere tekniske rapporter og internasjonale publikasjoner.

Jeg samarbeider med EFD Induction, Politehnica University of Bucharest, elektrovarmemiljøet i Trondheim og i Grenoble.
