摘要:
The fruitful progress toward light manipulation in reflective (R) or transmissive (T) geometry (half-space) has facilitated strong aspiration towards full-space wave control. Although R–T synergistic strategy promises large-capacity and integrated functionality, it imposes difficulty and challenges for direction of arrival (DoA) in full space via an ultrathin flat device. As of today, very limited demonstrations are reported for single-wavelength and linear-polarization operation in full space, significantly limiting the exploitable degrees of...
