Based upon the minimum thermal resistance law and the law of ratio effective thermal conductivity, the formulae that could be applied to calculate the effective thermal conductivity of thermal barrier ceramic/metal composites are presented.

Based on the Boltzmann transport theory and lattice Boltzmann methods,the characteristics of heat transport properties and the effective thermal conductivity of 1-3 composite material were investigated.

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.

Finally it introduces the application of RF conductance profile in analyzing and calculating the rough surface RF equivalent conductivity and optimizing the technical process of RF microwave devices.

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.
