To explore this challenge, the team studied cavity resonators.

From Science Daily

These resonators significantly intensified the incoming light, allowing the team to observe HHG at both even and odd THz frequencies, an exceptional accomplishment.

From Science Daily

From the discovery four years ago that a pair of gold flakes creates a self-assembled resonator, researchers have now developed a method to study various fundamental forces.

From Science Daily

"Instead of focusing on the performance of single-resonator systems, we instead took into account the way these resonators interact, which opened up new possibilities," Naik explained.
