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 ($\hat{I}{\mu }_{\perp }$) and axial ($\hat{I}{\mu }_{\parallel }$) components, play a central role in…
