Jack Eichenberger [Google Scholar] 

Jack Eichenberger is a third year Electrical Engineering PhD student who joined the RF Microsystem group in August of 2017. He passed his qualifying exam in the fall of 2019. Jack is currently serving as a GTA. He was awarded the Ohio State University Fellowship during the 2017-2018 school year, as well as the AFRL Student/Faculty Fellowship during the summer of 2019 and GRA in 2018-219. Jack’s research interests include ultrawideband antennas, antenna arrays, and metasurfaces. He designed, fabricated, and tested an ultrawideband Vivaldi antenna operating from 2.5 to 57 GHz. Current projects include beam steering by mechanical actuation and a magnetically reconfigurable metasurfaces in collaboration with Prof. Renee Zhao’s group in the Department of Mechanical and Aerospace Engineering (e-mail: 


Jordan Ramsey [Google Scholar] 

Jordan received her B.S. in Computer Engineering at the University of Maryland-Baltimore County (UMBC) , in 2016. She joined the RF Microsystems group and started her PhD at Ohio State in the ECE department in August 2017. She arrived to the university as a graduate fellow. Before starting at The Ohio State Jordan has had internships at UMBC in high performance computing, modeling of Parkinson's patient’s motor ability and touch interaction in the operating room, Livermore national lab in technological policy and business relations, Johns Hopkins University focusing on image based calibration of motion estimation algorithms, and at Oak ridge national laboratory investigating the effects of routing procedures on total vehicle emission. In May 2019 Jordan completed her Ph.D. qualifying exam. During the course of her time in the Microsystems group she has contributed to the MEMS pulmonary artery banding device project for the treatment of congenital heart disease and is currently working on reconfigurable reflectarrays (email:
