The IEEE Washington Section calendar pulls content from the Washington Section’s vTools Events feed, the Northern Virginia Section’s vTools Events feed, and the Baltimore Section’s vTools Events feed, since there is significant overlap between the two sections’ members. (vTools Events is the IEEE-operated database that contains all IEEE events globally. To be useful, it requires filtering at the section level.)

Smaller and Faster: Magnetic Nanowires at Microwave Frequencies
2019-08-27 @ 17:30 - 19:30 EDT
Co-sponsored by: IEEE Nanotechology Council and IEEE MTT Chapter
ABSTRACT: This talk focuses on the dynamic properties of magnetic nanowires. After a short introduction to ensemble of non-interacting nanowires, the speaker moves to discuss a strongly interacting nanowire system (defining the density of nanoelements in applications). The dominating role of the long-range magnetostatic dipolar interactions is demonstrated in establishing a configurational reorientation transition. The interaction of magnetic nanowires with electromagnetic waves is controllable due to its size and shape sensitivity. The results of modeling the electrodynamic diffraction problem show how the properties of these flexible systems of ordered magnetic nanowires can be controlled and tuned up to the THz frequency range. Magnetic nanowire systems are serious contenders for novel microwave devices, based on the propagation of electromagnetic waves (EMWs) in the nanostructures, and they are already utilized in microwave devices, photonics, and plasmonics.
