Maxwell relation
3.The optical constants are studied of extremely thin metallic(Ag and Al)and dielectric films (ZnS and SiO_2) by using the attenuatted total-reflection(ATR) techniques. The microstructure parameters of metal films are determined from the effective Lornetz oscillator and Maxwell-Garnett theory, and the relation between the variations of optical constant s and microstructares are revealed.
4.were analyzed the relaxation mechanism, the relation between Debye relaxation & Maxwell-Wagner effect.
5.According to the Maxwell equations and the Floquet theorem, the dispersion relation of the coaxial slow wave structure in MILO is analyzed, and the relations between the operating frequency and the structure parameters are obtained. The results show that changing the cathode radius would not influence the frequency of MILO, so the impedance can be adjusted conveniently by changing the cathode radius without frequency altering.
6.made the energy analysis of the device, and proposed the nonlinear relation of the kinetic energy to the elevation angle of the pitch part, and derived the electromechanical dynamics differential equations of the device based on the Lagrange-Maxwell equations;
