Application of metamaterial in microwave energy absorption

Metamaterial as artificial material having exceptional electromagnetic properties recently comes up great attention. In particular, metamaterial with both negative permittivity and permeability have attracted widespread interest. Such composites can be constructed from an array of metallic pieces with special shapes. In this paper, heating characteristics are discussed for such metamaterial. Simulated result reveals such new material concept will reveal special heating effects to accelerate chemical reaction and metal powder heating.
