Projectdetails

Introduction

Our everyday life is unimaginable without wireless information and communication technologies. Since 2019, 5G digital systems offer improved speed, bandwidth, and decreased energy consumption. Mobile operators invest $160 billion worldwide in the deployment of 5G each year.

Challenges with Current Technologies

Over the last decades, RF filters based on Surface Acoustic Wave (SAW) occupied the entire market. However, their usage for 5G high-band (26 GHz in EU) is impossible. Moreover, the utilization of Bulk Acoustic Waves (BAWs) is still left to be explored due to their significant damping, challenges with confinement, and complex fabrication.

Proposed Solution

The solution is offered by the propagating excitation in the spin system of a solid magnetic body - Spin Waves (SWs), which can efficiently replace acoustic waves in the RF devices for all frequency bands.

Key Advantages of Spin Waves

The key advantages of SWs are:

  1. Frequency range from 1 GHz up to hundreds of GHz.
  2. Manufacturability of SW transducers using conventional photolithography.
  3. Strong confinement of SWs.
  4. Additional nonlinear functionalities.

Previous Work

The ERC StG MagnonCircuits finished with utmost success (40 articles) and delivered the methodology and know-how for fabrication and characterization of magnonic nano-structures. It explored SW physical properties in them and identified robust, reliable, and efficient phenomena for applications.

Future Work

In the 5G-Spin project, I will develop fully functioning, bias field-free, and industry-ready SW-based RF filters and multiplexers for mid- and high-band 5G communication systems.
