The procedure of the growing of a single nanoprotrusion on a tungsten carbide field emitter surface was described. This aim is achieved by simultaneous action high electric fields and enough high temperatures on the emitters (thermofield treatment) at special regime. The values of emission current, current density, emission angle and reduced brightness of the single nanoprotrusions-emitters are comparable...
A device capable of transmitting images with sub-wavelength resolution is proposed. The structure is formed by an array of parallel conducting wires (wire medium) and effectively operates as a telegraph which captures a distribution of the electric field at the front interface and transmits it to the back side without distortions. This regime of operation is called canalization and is inherent in...
