Probing subwavelength in-plane anisotropy with antenna-assisted infrared nano-spectroscopy

s-SNOM is a powerful tool, but it is less sensitive to in-plane variations. Here the authors present a method to improve this with a metallic microdisk antenna, which they demonstrate by probing in-plane phonon responses.
