Mohamed Emara
I am currently a PhD Candidate in the Department of Electronics at Carleton University. My PhD research is focused on designing leaky-wave antennas and metasurfaces (transmitarray and reflectarray) for millimeter-wave beamforming. This research supports communication and instrumentation applications for 5G and 6G wireless networks.
