Abstract

3D metasurface structures can achieve higher performances (e.g., wider FOV, broader bandwidth, higher efficiency) than their 2D counterparts due to the extra degrees of freedom available to designers. A promising technique to fabricate 3D metasurface structures is membrane projection lithography. In this paper, we present a 3D metamaterial unit cell that is designed to achieve broadband asymmetric transmission in the mid-wave infrared (MWIR) regime. The structure was optimized by pairing a genetic algorithm with a fast periodic finite element boundary integral solver. The metasurface design has a max y - to x · polarization light efficiency of 80% in the forward direction, while transmitting less than 10% in the reverse direction. Moreover, this structure can be fabricated using the membrane projection lithography technique.
