Join SIAM in hosting Joseph Gaone for a talk revolving around Permittivity
Abstract: In microwave heating the complex permittivity determines how the energy propagates and is absorbed by materials. It is necessary to have an accurate way to experimentally determine this parameter from materials for use in modeling and engineering microwave applications. I will discuss this work of measuring permittivity from a summer internship for the Air Force Research Laboratory at Kirtland Air Force Base. The second half of the talk will discuss how permittivity can be used to control the uncontrollable microwave heating event known as thermal runaway. This unfavorable effect can lead to catastrophic failures of materials. This new proposed method of control may lead to better efficiency in microwave devices.
