AI Article Synopsis
- - The letter proposes a non-reciprocal electromagnetic metasurface that utilizes a highly nonlinear liquid metamaterial to create a significant difference in transmission coefficients, reaching up to 0.95 between forward and backward directions.
- - This metasurface is designed to be thin, only comparable to the wavelength, making it efficient for practical applications.
- - The high nonlinearity of the liquid metamaterial requires less radiation power to trigger nonlinear effects, and the concept has been validated through numerical simulations.
Article Abstract
In this Letter, we propose the design of a non-reciprocal electromagnetic metasurface, which uses a highly nonlinear liquid metamaterial as a source of non-reciprocity. We show that the proposed metasurface, whose thickness is comparable to the wavelength, can exhibit a difference between the transmission coefficients in the forward and backward directions of up to 0.95. Moreover, the particularly high nonlinearity of the liquid metamaterial enables the radiation power required to induce the nonlinear effects to be considerably reduced compared with natural materials. The feasibility of the proposed metasurface has been verified by numerical simulations.
