Abstract
Disclosed are a phase modulation surface unit, a phase modulation surface structure, and a terminal device. The phase modulation surface unit includes at least two phase-shifting layers which are stacked, where the phase-shifting layers each include: a first substrate; a second substrate; the first phase-shifting surface layer including at least one first electrode pattern extending in a first direction; the second phase-shifting surface layer including at least one second electrode pattern extending 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 tunable dielectric layer between the first phase-shifting surface layer and the second phase-shifting surface layer.
