Claim 0:
1. A metamaterial structure formed in a metal pattern, wherein the metal pattern is provided in an electrically interconnected form to perform a heating function,
wherein the metal pattern is formed so that, for both polarizations orthogonal to each other in a specific frequency band of microwaves, a relationship between a metal filling fraction (E) at which a metal is filled per unit area of the metal pattern and a microwave transmittance (T) satisfies an equation of T>(1-E),
wherein the metal pattern is provided in a structure in which a plurality of unit structures are continuously connected, and one unit structure is disposed per unit area of the metal pattern and is electrically interconnected with other adjacent unit structures,
wherein at least one electric dipole induced by a partial gap of the metal pattern is provided in the unit structure,
wherein the specific frequency band of microwaves is changed by selectively changing structural variables of the unit structure, and
wherein the structural variables comprise at least one of a size of the unit structure, a metal thickness of the unit structure, a metal width of the unit structure, a separation distance of the electric dipoles, and a size of the electric dipoles.
