“…The excited guided wave undergoes negative refraction at the lateral boundaries of the waveguide, making the waveguide to radiate predominantly in the lateral and back directions (see inset (a) in Fig. 3) [14][15][16][17][18]. Thus, if a point source of TM-waves is placed next to the slab (i.e.…”

In this paper we demonstrate the possibility of backward radiation from a negative permittivity planar (slab) waveguide. Furthermore, we show that backward radiation can be used to achieve sub-wavelength imaging of a point source placed close to such a slab or to a periodic layered system of slabs. Finally, we demonstrate backward-radiation-based imaging in the case of realistic materials operating in the THz regime, such as polaritonic alkali-halide systems.

“…Such an antenna has been realized experimentally on the form of a tube-like DNG waveguide [14]. The antenna was tuned to radiate at the frequency of 3 GHz, where the metamaterial forming the waveguide had negative values of permittivity and permeability.…”

This paper is concerned with the problem of global robust exponential stability for a class of interval cellular neural networks with time-constant delays. By introducing a novel Lyapunov-Krasovslii functional combining with the idea of delay fractioning, some delay-dependent conditions are derived in terms of the linear matrix inequality, which guarantee the considered interval delayed cellular neural networks to be global exponentially stable. Moreover, the conservatism can be notably reduced as the the fractioning goes thinner. A numerical example is provided to demonstrate the advantage of the proposed result.977 978-1-4244-6044-1/10/$26.00 ©2010 IEEE
