Nanowire waveguide made from extremely anisotropic metamaterials
Exact solutions are obtained for all the modes of wave propagation along an anisotropic cylindrical waveguide. Closed-form expressions for the energy flow on the waveguide are also derived. For extremely anisotropic waveguide where the transverse permittivity is negative 0 while the longitudinal permittivity is positive 0 , only transverse magnetic TM and hybrid modes will propagate on the wave...
متن کاملMechanical Behavior of Concrete, Made with Micro-Nano Air Bubbles
Nano materials have been widely used in laboratory and industrial scales in order to improve various properties of concrete and concrete mixture. The mainstream practice of the researches in this field is to add metallic nano-particles into the concrete mixture. The present research focuses on adding Micro-Nano Air Bubbles (MNAB) into water before mixing it with aggregate and cement mixtures. I...
متن کاملOptical mode structure of the air waveguide.
Analysis is performed on propagation of light in long-lived optical waveguides in air generated by arrays of femtosecond filaments. Mode structure, leakage losses, and coupling efficiency are studied analytically and numerically as a function of wavelength and time delay after the waveguide-initiating filaments.
