Barbaros Aslan, Ph.D., CFEI

Dr. Aslan specializes in issues pertaining to electrical and electronic engineering, especially as they relate to semiconductor devices, RF/Microwave/THz electronics, and micro/nanofabrication. He has extensive experience with fabrication equipment and high-frequency characterization and simulation tools, along with related experience in software/algorithm development. His expertise further extends into wireless systems/communications (cellular, RFID and radar), as well as integrated-circuit packaging and power transmission/distribution.

Dr. Aslan received his Ph.D. in Electrical Engineering from Cornell University, where his research focused on the development of a new nanoscale solid-state electronic device for generating THz radiation. His work included thermal/electrical modeling and simulation, fabrication/process development, and characterization. He also gained significant experience in ohmic contacts, thermal management, and coupled device-circuit simulations at the high-field transport level.

Prior to his graduate studies at Cornell, he worked for defense contractors: Herley Industries Inc. and Anaren Microwave Inc. At Herley, he designed, simulated (at electromagnetic and circuit levels), and characterized broadband microwave low-noise amplifiers (LNA). Subsequently, he was awarded an academic grant by Herley to develop in-house software to implement his novel method that predicts high-frequency transistor performance for a given set of LNA specifications. At Anaren, he was involved in the optimization of passive high-frequency components using three-dimensional electromagnetic simulators and also developed software modules to analyze and extract information from measured S-parameter data collected from these parts.

Dr. Aslan also has broad teaching experience, taught courses in Microwave Engineering/Measurements and Microelectronics. Dr. Aslan served as an Academic Excellence Workshop coordinator for a year in the ECE department at Syracuse University.
