Unified Homogenization of Photonic/Phononic Crystals: Controllable First-band Negative Refraction
Sia Nemat-Nasser
It is shown, for the first time, that negative refraction with positive phase velocity refraction can be realized (and controlled) over a wide range of frequency on the first (lowe…

Refraction Characteristics of Phononic Crystals
Sia Nemat-Nasser
The refraction properties of phononic crystals are revealed by examining the anti-plane shear waves in doubly periodic elastic composites with unit cells containing rectangular and…
