Classification: CPC G  C  Y | IPC G

Claim 1:
2. The reconfigurable mask of claim 1, wherein the water storage layer stores water and:
the first interface is configured to split water into oxygen and hydrogen ions in response to a first voltage, applied across the first electrode and the second electrode, the first voltage generating a first electric field, at least some of the hydrogen ions propagating towards the first hydrogen loading region via at least one of the first electric field or diffusion, to change the first concentration of hydrogen ions in the first hydrogen loading region and the first transmission, absorption, phase shift, and/or reflectivity of the first hydrogen loading region; and
the second interface is configured to split water into oxygen and hydrogen ions in response to a second voltage, applied across the first electrode and the third electrode, the second voltage generating a second electric field, at least some of the hydrogen ions propagating towards the second hydrogen loading region via at least one of the second electric field or diffusion, to change the second concentration of hydrogen ions in the second hydrogen loading region and the second transmission, absorption, phase shift, and/or reflectivity of the second hydrogen loading region.
