Abstract :
This paper investigates the focusing of the backscattered microwave by using a flat left-handed materials (LHM) lens. Results show that the use of flat LHM lens does significantly increase the intensity of the backscattered microwave from the target. As such, microwave target detection and imaging with flat LHM lens can be highly desired with sub-wavelength resolution. For practical LHM lens, the imaging resolution would be worse than that in the simulation, somewhat like the case shown an experiment wherein the sub-wavelength imaging resolution for future systems with flat LHM lens can also be desired
