The Landauer 'residual resistivity dipole' is a well-known concept in electron transport through a disordered medium. It is formed when a defect/scatterer reflects an impinging electron causing negative charges to build up on one side of the scatterer and positive charges on the other. This charge imbalance results in the formation of a microscopic electric dipole that affects the electrical resistivity of the medium.

- The study explores a complex interaction between phonons (sound waves), magnons (spin waves), and photons (light waves) in a specially designed 2D multiferroic material made of elliptical nanomagnets on a piezoelectric substrate.
- When surface acoustic waves launch into the substrate, they cause the magnetizations of the nanomagnets to oscillate, leading to the generation of confined spin-wave modes (magnons).
- This interaction is then harnessed to create an ultra-efficient sub-wavelength electromagnetic antenna, achieving significantly higher radiation efficiency and gain compared to traditional antennas, supported by both experiments and simulations.
