摘要：A counter-intuitive phenomenon of propagation below cut-off in a waveguide filled with an anisotropic mu-negative metamaterial is investigated analytically, numerically, and experimentally. It is shown that the equivalent plane waves that make up the waveguide mode are inhomogeneous, and this fact is responsible for subwavelength guiding of electromagnetic energy. It was also found that the microscopic ('in-cell') magnetic field distribution in a waveguide filled with split-ring resonators may significantly differ from the distribution in the homogenized waveguide. However, spatial averaging of a numerically calculated magnetic field across the unit cell yielded a distribution that was very similar to the distribution in the continuous mu-negative material. Experimental waveguides filled with split-ring resonators were prototyped 思念母亲
