We show that a wavelength-controlled beam steering efficiency is improved by 0.888 deg/nm.This work was sponsored by National Research Foundation of Korea(2018R1A6A1A03025242); Ministry of Science and ICT, Republic of Korea (2020R1A2C3007007);enPublisher Copyright: © IEEE 2022.Metasurface Doublet-Integrated Bidirectional Grating Antenna Using Dual Polarization for Efficient Wavelength-Controlled Beam Steering202210.1364/CLEOPR.2022.CFA12E_0185166475990
