Tutorial EQ10: Magnetoelectric Antennas—Materials, Design, Simulation, Fabrication, Test and Applications

Monday, November 29, 2021
8:00 AM - 5:00 PM
Hynes, Level 2, Room 206

In this tutorial, we will discuss magnetoelectric antennas, talking about their materials, designs, simulation, fabrication, test and applications. This tutorial targets an audience interested in working in the area of magnetic, piezoelectric, multiferroic and magnetoeletcric materials and how they contribute to the performance of magnetoelectric antennas working from VLF (3~30 kHz) to UHF (300~3000 MHz) frequency range. The focus of the tutorial will be on the materials, designs, simulation, fabrication, test and applications of these magnetoelectric antennas.
