Electromagnetic Storage Technologies
This lecture covers various electromagnetic storage technologies, including magnetic storage with longitudinal and perpendicular recording, patterned magnetic media, magnetic-core memory, and magnetoresistive RAM. It also discusses electromagnetic actuation schemes, electrodynamic microbeam resonators, flexural plate wave resonators, electromagnetic micro-mirrors, electromagnetic loudspeakers, coils and inductors, electromagnetic motors, and polarized EM actuators. The instructor explains the principles, designs, and scaling considerations of these technologies, providing insights into their applications and limitations.
