A new mechanism for negative refraction and focusing using selective diffraction from surface corrugation
W. T. Lu, Y. J. Huang, P. Vodo +3
Refraction at a smooth interface is accompanied by momentum transfer normal to the interface. We show that corrugating an initially smooth, totally reflecting, non-metallic interfa…
Negative refraction and plano-concave lens focusing in one-dimensional photonic crystals
P. Vodo, W. T. Lu, Y. Huang +1
Negative refraction is demonstrated in one-dimensional (1D) dielectric photonic crystals (PCs) at microwave frequencies. Focusing by plano-concave lens made of 1D PC due to negativ…
Focusing by Plano-Concave lens using Negative Refraction
P. Vodo, P. V. Parimi, W. T. Lu +1
We demonstrate focusing of a plane microwave by a plano-concave lens fabricated from a photonic crystal (PhC) having negative refractive index and left-handed electromagnetic prope…
Microwave photonic crystal with tailor-made negative refractive index
P. Vodo, P. V. Parimi, W. T. Lu +2
Negative refraction and left-handed electromagnetism in a metallic photonic crystal (PC) wedge are demonstrated in free space for both transverse magnetic and electric mode propaga…
