Abstract: In this work, complementary split ring resonators (CSRR) based broadband monopole antenna is proposed. A variety of geometrical shapes are studied as a radiator to find out the radiator with the highest possible return loss bandwidth potential. It has been found that the semi-circularly shaped resonator has the widest VSWR<3 bandwidth. Therefore, a monopole antenna… Read More

Abstract: The problem of acoustic monochromatic radiation by boundary with a traveling distribution of phases of normal vibrational velocities is considered. It is shown that when the spatial frequency of the traveling phase of normal velocities approaches the wave number in the medium, the energy transfer from boundary   into a “sliding” (with respect to the boundary)… Read More
