Theory for tailoring sonic devices: Diffraction dominates over Refraction
N. Garcia, M. Nieto-Vesperinas, E. V. Ponizovskaya +1
In the moderately long wavelength propagation regime, acoustic crystaldevices which size is of several wave lengths are studied by using thefinite-difference time domain method. It…
Zero Permeability Materials (ZmuM): A way out of the "Left Handed Materials" trap
N. Garcia, M. Munoz, E. V. Ponizovskaya +1
Recently it has been shown that due to losses the claims on observation of negative refraction using metamaterials are questionable. In this paper we discus an interesting case tha…
Calculations of the Effective Permitivity of a Periodic Array of Wires and the Left-Handed Materials
N. Garcia, E. V. Ponizovskaya
We present finite-differences time- domain calculations of the effective permitivity of a periodic array of Cu strip wires that are an ingredient needed in metamaterials for obtain…
