These short courses were offered in conjunction with the High Power Microwave Conference in Adelphi, Maryland. Continuing Education Unit (CEU) credits were earned for completion of these DEPS short courses.
Course 1. High Power Microwave Fundamentals Classification: Unclassified, Public Release Instructor: Duration: Half-day course, starts at 0800 CEUs awarded: 0.35 Course Description: This course will provide a basic introduction to high power microwave (HPM) systems, also known as radio-frequency directed energy weapons (RF-DEW). Topics to be covered include:
The course goals are to provide students with a basic physical understanding of the operation of HPM devices and systems and to foster an understanding of both the promise and limitations of specific technologies. Students will learn about the basic mechanisms through which electromagnetic radiation couples into an object (i.e., in-band/out-of-band, front-door/back-door) and the rudiments of RF hardening and shielding. Technology discussions will cover the basic types of narrowband HPM source types - linear beam, crossed-field and fast-wave devices - as well as wideband and ultra-wideband (UWB) sources and antennas. Appropriate choices of prime power, power conditioning, and antenna technologies will be discussed in the context of generic applications and practical constraints. At the end of the course, students should have some of the basic tools to necessary to make informed decisions regarding HPM technology (or at least have the knowledge to ask intelligent questions). An extensive list of open literature references, relevant industrial contact information, and U.S. government resources will be provided to supplement the course. Intended Audience: The course material is geared to benefit newcomers to the field of HPM/RF-DEW and/or managers with some background in science and engineering. Non-technical enrollees could profit from the insights they will gain into HPM capabilities and limitations and develop a further appreciation of the technological challenges faced by the directed energy community.

After receiving his Ph.D. in 1992, he joined Berkeley Research Associates, Springfield, VA, where he worked on pulsed-power and high-power microwave projects. He joined the Army Research Laboratory, Adelphi, MD, in 1994, where he pursued projects in electromagnetic effects and high-power microwave generation. In 1997, he joined the Vacuum Electronics Branch, Naval Research Laboratory, Washington, DC, where he is currently pursuing research projects involving microwave and millimeter-wave vacuum electronic devices using both single and multiple electron beams. In 2004, Dr. Abe was a Guest Editor of the IEEE Transactions on Plasma Science Special Issue on High Power Microwave Generation and, in 2005, he co-edited the Proceedings of the 7th Workshop on High Energy Density and High Power RF (RF2005). He has contributed sections and chapters to several books, including High Power Microwave Sources and Technologies edited by R.J. Barker and E. Schamiloglu and Modern Microwave and Millimeter-Wave Power Electronics edited by R.J. Barker, J.H. Booske, N.C. Luhmann, Jr., and G.S. Nusinovich. Dr. Abe is a member of the American Physical Society and the IEEE and is presently serving a term on the Executive Committee of the Plasma Science and Applications Committee of the IEEE Nuclear and Plasma Physics Society.
Course 2. High Power Microwave Systems Classification: Limited Distribution, US Only Instructors: Duration:Full-day course, starts at 0800 CEUs awarded: 0.7 Course Description: This course will provide an introduction to high power microwave (HPM) weapons by adopting a modular approach to the design and characterization of a high power microwave system. The objective is to provide an understanding of the system components and the attributes of the weapon system. The basic principles of microwave generation, propagation and interaction with materials will be addressed. HPM terminology, zero-order calculations and scaling issues will also be covered. The weapon system is viewed as consisting of five modules: prime power and power conditioning equipment, a microwave source and structures to couple the source to the propagating media, propagation media, and the target. The physical principles governing a module, module characteristics, and the influence and constraints of each module on total system requirements and effectiveness will be discussed. Following an overview of failure phenomenology at the component level, we will examine how these failures can be used to generate a probability of effects distribution for an electronic system. The probability of effects can then be incorporated into a fault tree analysis for estimating the probability of system or mission kill. Intended Audience: The short course assumes that the registrants hold undergraduate degrees in engineering or science and are interested in an overview of HPM systems at some technical depth. No specific knowledge is needed of HPM, electronics, physics of failure, or modeling and simulation. The class material is limited to audiences of U.S. government contractor employees and government employees. Non-technical managers could profit from the insights they will gain into HPM capabilities and gain further appreciation of the technological challenges faced by the DE community.

Course 3. High Power Microwave Effects Classification: SECRET, US Only Duration: Half-day course, starts at 1300 CEUs awarded: 0.35 Course Description: This course will provide a basic introduction to the subject of the effects of HPM energy on electronic systems. The course will cover the basics of what HPM is, how it is different from traditional Electronic Warfare (EW), how it couples into electronic system and how it produces effects that can range from temporary interference to longer term upset to permanent damage depending upon the intensity of the energy and its characteristics. Since HPM energy can reach electronics by coupling into a target systems via either intentional antennas (i.e. front door coupling) and/or non intentional antennas (i.e. back-door coupling) both will be covered. The course will also cover the statistical nature of HPM effects and how they are best described in terms of a probability of effect as a function of the incident field strength or power density on the target system. Finally we will cover how to estimate HPM effect levels using basic modeling and simulation tools and how to measure the effects as a function of the HPM source parameters. Topics Covered:
Intended Audience: This course is meant for scientist; engineers and engineering managers that have a basic background in electronics, but may not have extensive knowledge of electromagnetic energy and it effects. It is meant to be a basic introduction to the subject and an extensive course on the subject.
