Claim 10:
11. 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 the unit structure comprises a first linear pattern formed to extend in a first direction on a unit area of the metal pattern;
a second linear pattern formed to extend in a second direction on a unit area of the metal pattern so as to intersect the first linear pattern; and
a circular pattern provided in a circular shape around an intersection point of the first and second linear patterns and electrically interconnected with the first and second linear patterns.
