It is pointed out that the equivalent permeability and permittivity of honeycomb-structured absorbing materials are smaller than those of the absorbing layer,but the equivalent permittivity is reduced more significantly,so the equivalent permeability is more close to the equivalent permittivity.

The effective permeability and permittivity tensors are calculated,the dispersive curv.

The results show that the effective permittivity and effective permeability of the composite medium are negative simultaneously in C-band frequency region, and therefore ind.

In this paper, according to the law of electromagnetic induction, the device measuring the equivalent susceptibility of metals was designed, which can real-time measure the change of the equivalent susceptibility of liquid metals during the cooling process.

The thick ring resonators to achieve negative permeability andits left-handed behavior in perpendicular propagation;

Left-handed materials(LHM)have negative permittivity,negative permeability,and negative re- fractive index.

Based on the analysis of the negative permeability properties of double split-ring-resonator array(SRRA),a simplified structure called single SRRA was proposed and demonstrated.

In 1968, Veselago investigated a material with negative permittivity and permeability (left-handed materials) theoretically, and obtained novel results of negative refraction and reversed Doppler shift.
