The rapidly expanding 5G infrastructure will significantly increase antenna and wireless systems markets for 28 GHz and beyond. We have explored dielectric measurement methods spanning the frequency range between 1 MHz and 100 GHz. Two general types of measurement techniques, resonant and transmission, have been developed. Resonant methods are generally discrete frequency measurements that have high accuracy, specifically for low loss dielectrics with dissipation factors below 1%. Resonant dielectric measurement methods include: a dielectric post technique in the 1-10 GHz range, a split-cavity method between 15-20 GHz and a Fabry-Perot method between 20-60 GHz.
Transmission/reflection methods have the advantage of being broadband and cover a large frequency range (1MHz to 110 GHz) and are useful for higher loss materials. This webinar will present broadband dielectric properties for a wide range of materials including quartz crystals, fused silica, alkali and alkaline-earth modified glass, polymers and polymer composites. Fundamental dielectric relaxation mechanisms in the MHz to THz frequency range will be discussed for amorphous and crystalline materials along with their impact on dielectric permittivity and loss.
About the Speaker
Michael Lanagan joined the Engineering Science and Mechanics Department (ESM) at Penn State in July 2004. Before joining Penn State, he was a staff scientist at Argonne National Laboratory for 11 years where he conducted Department of Energy supported programs related to materials for energy storage and distribution. His current research focuses on high frequency properties of materials for magnetic resonance imaging and 5G. He has co-authored over 300 publications and 10 patents in the areas of superconductors, microwave dielectric characterization and energy storage in capacitors.
Dr. Lanagan received his B.S. degree in Ceramic Engineering from the University of Illinois and his Ph.D. in Ceramic Science from Penn State University.
