Abstract
A meta-surface water load includes a waveguide section, a water load section and two meta-surface plates; the water load section is arranged at a rear end of the waveguide section; the two meta-surface plates are arranged opposite on inner walls of two narrow sides of the waveguide section; the water load section includes a metal casing, a ceramic partition, a water inlet and a water outlet; the metal casing is mounted at the rear end of the waveguide section; cooling liquid flows in the metal casing, entering from the water inlet and leaving from the water outlet; the ceramic partition is for separating interior of the waveguide section and interior of the metal casing; a relative permittivity of materials from front to rear of each meta-surface plate is progressively increased, so that microwave in the waveguide section is propagated to the water load section in one direction.
