Metasurfaces consisting of different shapes of resonant units are used to manipulate light beams at subwavelength scales. In many cases, interactions among the resonant units are suppressed or avoided because of mode splitting in metasurfaces. Here we theoretically and numerically investigate metasurfaces composed of multiple antennas with anti-Hermitian coupling in a single layer. By utilizing the anti-Hermitian coupling, the results show that antennas with similar resonance frequencies at a subwavelength distance can individually absorb their corresponding frequency photons. The antennas whose reflection phase can be tailored by changing the number of antennas have the same resonance frequencies. This Letter paves the way for various potential applications in broadband absorption, photon sorting, image sensors, and phase modulation.
