Title:
PHASE MODULATION SURFACE UNIT, PHASE MODULATION SURFACE STRUCTURE, AND TERMINAL DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/040445
Kind Code:
A1
Abstract:
Disclosed in the present invention are a phase modulation surface unit, a phase modulation surface structure, and a terminal device. The phase modulation surface unit comprises at least two phase-shifting layers which are stacked, wherein the phase-shifting layers each comprise: a first substrate; a second substrate arranged opposite to the first substrate; a first phase-shifting surface layer located on the side of the first substrate facing the second substrate, the first phase-shifting surface layer comprising at least one first electrode pattern extending in a first direction; a second phase-shifting surface layer located on the side of the second substrate facing the first substrate, the second phase-shifting surface layer comprising at least one second electrode pattern that extends in a second direction and has one-to-one correspondence to the first electrode pattern, and the orthographic projection of the second electrode pattern on the first substrate intersecting with that of the corresponding first electrode pattern on the first substrate; and an adjustable dielectric layer located between the first phase-shifting surface layer and the second phase-shifting surface layer. The phase modulation surface unit can realize continuous and accurately controlled phase modulation, has a relatively large phase-shifting range, and can save manufacturing costs.
