Abstract

We have numerically investigated the photon-magnon coupling in the system of coupled anapole resonators (metasurface). A strong spin-number-normalized coupling strength (single spin-photon coupling) $g_{eff}/2\pi \sqrt{N}$ was reached up to 0.276 Hz (g_eff/2π = 310 MHz) at a frequency of 9.7 GHz compared to the spin-number-normalized coupling strength in a single splitring resonator (SRR) $g_{eff}/2\pi \sqrt{N}=0.097 \text{Hz}\left(g_{eff}/2\pi =270\text{MHz}\right)$.
