Field Energy Approach for Homogenization of Metamaterials

Objectives: In recent years metamaterials have been widely accepted to explore its new and unique electromagnetic properties. Metamaterials differ from conventional materials in terms of its structure i.e. they have inclusions in place of atoms and molecules. It is because of this uncommon structure and geometry that metamaterials show these electromagnetic properties. Methods: To know about these responses in detail there is a nee d to find parameters like permittivity and permeability for these materials. To simplify this complicated process of calculation of parameters, homogenization techniques are used. Findings: So, this paper deals with the study of homogenization technique called Field Energy Method and retrieval of parameters from it. It also focuses on comparing Field Energy Method with Average Method and proving that earlier is more efficient than the later.
