Jack Eichenberger Graduated with Ph.D.

Jack Eichenberger graduated with Ph.D. in Electrical and Computer Engineering at the Ohio state University in May 2022. His Ph.D. dissertation is titled ” Novel Ultra-wideband Vivaldi Antenna and Mechanically Reconfigurable Antenna Arrays”. Jack joined Agile RF Systems, CO after graduation. We wish Jack the best in the step of his life!

GRA Positions

Prof. Nima Ghalichechian is looking for motivated PhD students to join the mmWave Antennas and Arrays Lab. The group’s research is on design, fabrication, and testing of antennas and arrays. Please review our group’s prior publication and research at Qualified Ph.D. students with background in applied electromagnetics, especially, antennas or microwave engineering are encouraged to apply by emailing their CV and a short note to Prof. Ghalichechian ( Thank you!
