“…Similar control of surface plasmon waves can also be achieved with plasmonic grooves, which consist of periodic nanoscale indentations, and waveguide structures 25 , 26 . These innovative plasmonic structures have paved the way for a myriad of applications, including enhanced biosensing 27 , improved optical devices 28 , and the development of highly efficient energy harvesting systems 29 . However, most of the plasmonic metasurface structures designed so far are based on the manipulation of the electric field component of the radiation, whereas to enhance magnetic transitions in EPR spectroscopy, only the magnetic component is important.…”

The increasing miniaturization of everyday devices necessitates advancements in surface-sensitive techniques to access phenomena more effectively. Magnetic resonance methods, such as nuclear or electron paramagnetic resonance, play a crucial role due to their unique analytical capabilities. Recently, the development of a novel plasmonic metasurface resonator aimed at boosting the THz electron magnetic response in 2D materials resulted in a significant magnetic field enhancement, confirmed by both numerical simulations and experimental data. Yet, the mechanisms driving this resonance were not explored in detail. In this study, we elucidate these mechanisms using two semi-analytical models: one addressing the resonant behaviour and the other examining the orientation-dependent response, considering the anisotropy of the antennas and experimental framework. Our findings contribute to advancing magnetic spectroscopic techniques, broadening their applicability to 2D systems.
