Laboratory overview
Applied Magnetic Systems Laboratory, Ariel University
The Applied Magnetic Systems (AMS) Laboratory is a research laboratory at Ariel University headed by Dr. Nezah Balal, Senior Lecturer in the Department of Electrical and Electronics Engineering. The laboratory develops permanent-magnet systems and millimeter-wave technologies from physical design through fabrication and measurement, and hosts postdoctoral researchers and graduate students. The official laboratory page is on the Ariel University website; this page is a short overview on Dr. Balal's personal site.
