Our industry experts will discuss the background and theory behind radome simulations, go over the basic electromagnetic theory and propagation through radomes. The course will discuss material selection and properties and look at the thermal and environmental considerations. Dr. Jonothan Pryor (Resonant Sciences) will discuss the background and theory behind radome design and their application. Ron Lavin (Boeing) will go over radome analysis and applications and will look at radome simulations and techniques. Steve Nichols (NSI-MI Technologies) will cover the practical measurement standards and techniques including performance and testing and compliance to standards.

Dr. Jonothan Pryor
Resonant Sciences
Ronald (Ron) Lavin
The Boeing Company
Dr. Jonothan Pryor is a Senior Research Engineer at Resonant Sciences with over 20 years of experience in antenna and radome design and analysis, RF materials characterization, and the design and characterization of advanced RF composite structures for signature control. He has expertise in frequency selective surfaces (FSS), material and system measurements, radomes, phased arrays, and conformal antennas on both manned and unmanned aircraft. His antenna experience includes the design of conformal VHF/UHF antennas, several single and dual-band slotted waveguide arrays operating at X-, Ku-, and Ka-bands, tri-band corrugated horn antennas, and ultra-wideband phased array antennas. His radome experience includes composite dielectric radomes and hybrid composite/FSS radomes for multi-band and broadband applications. His radomes are currently deployed on numerous commercial and military platforms.

Dr. Pryor graduated Summa cum Laude with Bachelors of Science degrees in both Physics and Electrical Engineering from Southern Methodist University in 1994. He received his Masters of Science and Ph.D. from The Ohio State University in 2000 and 2003, respectively, where he completed research with Dr. Ben Munk in FSS designs for near-infrared applications. He worked for Harris Corporation, ATK-Space Systems, and Matrix Research prior to co-founding Resonant Sciences, located in Beavercreek, OH, in 2015.
Ronald (Ron) Lavin is a Boeing Technical Fellow leading antenna and computational electromagnetics efforts at The Boeing Company. He received the M.Sc. degree in Computer Science with Distinction from DePaul University, Chicago, in 2000, and the B.Sc. in Electrical Engineering degree from Florida International University, Miami, in 1995. He has been with Boeing since 2001, supporting satellite, fixed wing aircraft, helicopter, and proprietary programs. He is a member of the IEEE and Vertical Flight Society, member of the industrial Advisory Board for Embry Riddle Aeronautical University, was for many years the Boeing focal for the Arizona State University Advanced Helicopter Electromagnetics consortium under Dr. Constantine Balanis, and holds has 10 patents. His research interests include novel antennas, structural windows, radomes, engineered dielectrics, electromagnetic effects, and computational algorithms. He is based in Mesa, Arizona and is a former FAA spectrum engineer.

Lydell Frasch
The Boeing Company (Retired)
Steven R. Nichols is the Manager of Instrumentation Products at NSI-MI Technologies, where he leads the development of electronic standard products and instruments. Steve has over 30 years of experience in engineering design and technical management, much of it spent advancing the state of the art in antenna, radar cross section, and radome measurement instruments and systems.

Steve received a Bachelor of Electrical Engineering degree from the Georgia Institute of Technology. He is a Senior Member of the IEEE and served on the Board of Directors for the IEEE Atlanta section. Steve is also a Senior Member of AMTA and served on the AMTA Board of Directors from 2014-2017 as Technical Coordinator, President, and Past-President.
Bio: Dr. Lydell L. Frasch is a retired Boeing Technical Fellow. He had over 32 years of electrical engineering and electromagnetic scattering related technical experience with the Boeing Company, a total of 36 years in electromagnetics and 40 years as a practicing engineer. He currently works as a consultant in the areas of the electromagnetic characterization of special materials, such as composites and absorbers, the development of in-field measurement devices for characterizing materials, electromagnetic scattering phenomena with applications in radar cross-section analysis/measurement, and antenna measurement. Before joining Boeing as a senior RCS engineer in 1988, he was a graduate research assistant at Michigan State University. Prior to that he worked for the Dow Chemical Company, Midland Division, Midland, MI, from 1980 to 1983 on in-field, analytical measurement instrumentation. Dr. Frasch received the B.S. degree in physics in 1979 and the B.S. in Electrical Engineering in 1980, both from the South Dakota School of Mines and Technology, Rapid City, South Dakota. He received the M.S. and Ph.D. degrees in electrical engineering from Michigan State University, East Lansing, Michigan, in 1983 and 1987, respectively. Dr. Frasch is a Fellow of AMTA, a senior member of the IEEE, a member of ASTM International Committee D9 on electrical insulating materials, Tau Beta Pi, Eta Kappa Nu, Sigma Pi Sigma, and Sigma Xi.
