Abstract: Microwave-assisted magnetic recording (MAMR) is one candidate for next-generation perpendicular magnetic recording. Theoretical analysis, experiments and simulations have contributed to MAMR research and spin stand experiments have shown the high potential of MAMR. Also, it has been announced that commercial MAMR HDDs will be shipped in 2019. Stable oscillation is one of the most important factors for the spin-torque oscillators (STO) used in a MAMR system.

In this work micromagnetic model simulations were performed to investigate STO integrated into the MP-TS gap of the write head (integrated STO). First, the oscillation states of a tilted STO were investigated in a model comprising the write head, STO and medium soft underlayer (SUL). We found that inserting the STO into a non-parallel MP-TS gap resulted in more stable oscillation compared with an STO in a MP-TS gap perpendicular to the medium surface. Second, we performed full micromagnetic simulations of the write head, STO, SUL and recording layer (RL) and the oscillation of the tilted STO was investigated. We found that the RL affected STO oscillation to some extent, however, the effect was smaller than that from the write head. We also discuss medium recording simulations carried out using the full model.

 

Short Bio: Dr Yasushi Kanai is a Professor of the Engineering Department at Niigita Institute of Technology, Kashiwazaki, Japan.

Abstract

Dr. Alwan will present an overview on ultra-wideband (UWB) communication systems including ultrawideband arrays, reduced hardware and power efficient communication back-ends, and millimeter-wave technologies for 5G applications.  Since 2009, Dr. Alwan has been involved in a number of projects related to the design, fabrication, and measurement of antennas and RF systems, with emphasis on UWB applications. Specifically, focus of his current research is on developing a new class of transceivers for high data rate secure communications with interference suppression capabilities. Such systems enables instantaneous transmission and reception over a wide frequency bands using UWB arrays. Concurrently, coding techniques are applied to achieve significant hardware, cost, and power reduction. Simultaneous transmit and receive capabilities are also part of his research to achieve multipath and self-interference cancellation. Also, channel coding and code division multiplexing are used for interference mitigation and multi-user detection. Alongside, Dr. Alwan am pursuing intensive research in millimeter wave systems which involves antenna arrays and RF front-ends design, fabrication, and packaging using latest state-of-the-art technologies.

 

SHORT BIO

Elias A. Alwan has recently joined FIU as Assistant Professor. Before that, he was a senior Research Associate at the ElectroScience laboratory at the Ohio State University. Dr. Alwan received his Bachelor of engineering (BE) degree in computer and communication engineering (summa cum laude) from Notre Dame University–Lebanon, in 2007, his Master of Engineering (ME) in electrical engineering from the American University of Beirut, in 2009, and his PhD in electrical and computer engineering from the Ohio State University, in January 2014. He is an IEEE member since 2008 and a Phi Kappa Phi member since 2010. His current research interests include electromagnetic theory, ultra wideband antenna design, and RF and millimeter wave systems.
