Bounds on the Uniaxial Effective Complex Permittivity of Two-phase Composites and Optimal or Near Optimal Microstructures

Kshiteej J. Deshmukh, Graeme W. Milton

Electromagnetic materials with a uniaxial effective permittivity tensor, characterized by its transverse (${\epsilon }_{\perp }$) and axial (${\epsilon }_{\parallel }$) components, play a central role in th…
