Part III: Dielectric Properties of Foods and Bioproducts

Thursday, June 1st from 11am-12pm
Presenters: Pranjali Muley and Candice Ellison, Louisiana State University

Knowledge of dielectric properties of materials plays a major role in microwave design for any particular process. Dielectric properties provide information about how the material will interact in the presence of electromagnetic energy during microwave heating. As the application of microwave and RF heating in food industry is gaining momentum, significant work has been performed on measuring the dielectric properties of various foods and bioproducts. This webinar will focus on understanding the dielectric properties of different foods and bioproducts and their relationship with other material properties (temperature, density, moisture content, etc). This presentation will also give a brief overview of dielectric properties and measurement techniques. Application of dielectric properties in system design and numerical modeling will also be discussed.

Part II: Material Characterization from DC to mm-wave and THz

Thursday, April 27th from 11am-1pm EDST
Presenter: Say Phommakesone, Keysight

From stealth materials to dielectric substrates, microwave food products to biofuels, accurate characterization of their electromagnetic properties from DC to THz frequencies provide engineers with critical information needed for material and circuit design, modeling, new material research, health and safety, manufacturing, quality control, and more. Many measurement methods exist, but which to choose is often a mystery. My intent with this seminar is to clear the air by providing an overview of measurement methods, with strengths, limitations and applications of each.

Part 1: Introduction to Dielectric Properties for Microwave Processing of Materials
Thursday, March 30th from 11am-12pm EDST
Presenter: Shawn M. Allan, Allan Materials

Abstract: Microwave and RF heating offer significant opportunities for cost savings in manufacturing, from food products to ceramics. The ability to generate heat within the product saves both time and energy. The manner in which products respond to microwaves can vary greatly from heating vigorously or barely at all, and from uniformity to localized hot spots. These variations are due in large part to the materials' dielectric properties. Dielectric properties determine the degree to which microwave power is transmitted, absorbed, and reflected by materials, and therefore also the degree and uniformity of heating.

Knowing the dielectric properties and how they change with frequency and temperature, allows process developers to create better microwave heating profiles. Property data is essential to enabling accurate microwave modeling efforts. This webinar will cover basics of dielectric properties and their relationship to physical material parameters and response. A few examples of measurement options will be shared. Case studies will be provided of the use of dielectric properties in understanding microwave processing results and development of heating strategies.

Bio: Shawn Allan is a materials engineer (B.S. Alfred University, M.S. Georgia Tech) and Vice President of Lithoz America LLC, a New York based subsidiary of Lithoz GmbH, which specializes in additive manufacturing of ceramics. Shawn's past roles include President of Allan Materials Inc., and Senior Program Manager at Ceralink Inc, where he acquired 11 years of experience in microwave and RF processing of materials ranging from drying, hydrothermal processing, polymer melting, binder removal, high temperature calcination reactions, and sintering of ceramics and metals. The use of dielectric property data figured prominently in that work, with several examples published related to process development and modeling.

Join us for an introduction to what dielectric properties are, why they are important to a researcher or developer and what you can learn from them.

Instructor: John M. Osepchuk, Full Spectrum Consulting

Magnetrons are the accepted norm for microwave power applications (e.g. heating):; the microwave oven, domestic and commercial: also for industrial applications at 915 MHz as well as industrial and specialized commercial applications at 2.45 GHz at power levels exceeding 2 kW. This webinar presents an overall review of these tubes, their history and their future. We will concentrate on the cooker magnetron at 2.45 GHz that is used in microwave ovens, but there will be brief reviews of the magnetrons at `915 MHz and 5800 MHz.

Course content will be of interest to product developers & engineers whose work relates to domestic and commercial microwave ovens, as well as process developers, systems engineers interested in industrial heating systems.

Topics include:

  • History of magnetron development in USA, Far East & Russia.
  • Overall view of key magnetron components: anode, cathode, pole pieces, etc.
  • Theory and experiment about normal magnetron operation.
  • A brief review of the theories related to abnormal phenomena i.e. damage to anodes triggering possible serious RFI problems near end of life.
