Dr. Frank B. Gross
Dr. Gross has over 36 years of experience in the areas of beamforming, array processing, array design, adaptive arrays, smart antennas, electromagnetics, antennas, communications, and signal processing. He has served as university professor, SAIC Chief Scientist, and Boeing Technical Fellow. He has worked on many projects including satellite beamforming, frequency selective surfaces (FSS), radomes, metamaterials, radar waveform design, shallow-water synthetic aperture sonar (SAS), passive radar receiver design and evaluation, FM-CW fuze systems,satellite antennas including helices, fractal arrays, broadband antennas, and direction finding antennas. He is the inventor of the Thue-Morse metamaterial substrate to support broadband antenna performance.
He has served as PI and/or Boeing Technical Fellow on numerous projects working with SOCOM, DARPA, ONR, NCSC/NSWC,NAVAIR, NASA-Langley, NASA-Kennedy, GTRI and the Harry Diamond Labs. He helped to develop “quiet” waveforms for terrain following/terrain avoidance(TF/TA) radar for SOCOM which supported the “Silent Night” program. He also worked with NASA/Langley on developing their pulsed anechoic chamber for radar cross section measurements.
Dr. Gross formerly served for 18 years as a professor at the Florida State University teaching courses on propagation, antennas, smart antennas, numerical methods, radar, sonar, signals and systems, circuits, microwave engineering, and electromechanical dynamics. He also previously served as Associate Dean at the Georgia Southern University.
Dr. Gross has published over 60 journal articles, papers, and reports on the general topics of electromagnetics, electrostatics, antennas, and arrays. He is the author of the 2005 McGraw-Hill book entitled, “Smart Antennas for Wireless Communications with Matlab”. He the author of the 2015 book on “Smart Antennas”, McGraw-Hill. He is the author of a chapter on “Smart Antennas” in the 2007 3rd edition of the “Antenna Engineering Handbook” edited by John Volakis. He was also the Editor-in-Chief for the “Frontiers in Antennas” book by McGraw-Hill, 2011.
A new world of materials is emerging called "metamaterials" where physical properties are altered to achieve results that don't naturally occur in nature. Metamaterials are materials that use resonance properties to "cheat" nature and cause effects to occur that may benefit antenna radiation and possibly support "cloaking" devices. "Metamaterials" simply means materials that are beyond normal material properties. Their unique properties are created when resonance conditions are created. Often this is accomplished by creating cavities along the material surface that resonate at the design frequency. Switchable metamaterials can be used to dramatically reduce radar cross section or to modulate beam patterns for surface mounted antennas.
This lecture on metamaterials will cover the basic physics of these materials and will demonstrate several practical applications.
