Reversal of transmission and reflection based on acoustic metagratings with integer parity design
Phase gradient metagratings suffer from limits on conversion efficiency. Here, the authors show a refractive-type metagrating which can enable anomalous reflection and refraction with almost unity efficiency over a wide incident range and uncover how integer parity plays a role in higher order diffr...

| Sumario: | Phase gradient metagratings suffer from limits on conversion efficiency. Here, the authors show a refractive-type metagrating which can enable anomalous reflection and refraction with almost unity efficiency over a wide incident range and uncover how integer parity plays a role in higher order diffraction. |
