Abstract

The dispersion properties of electromagnetic waves propagating in a tangentially magnetized ferrite plate with bigyrotropic properties in combination with magnetic dissipation are considered. A complex (due to dissipation) dispersion relation is obtained. Branches of dispersion curves that are typical only of a dissipative medium are found. The critical value of the damping parameter that separates two significantly different regions of dispersion is obtained. It is shown that the critical damping parameter corresponds to the transition of magnetic oscillations from the periodic regime to the aperiodic one.

电磁波在耗散介质中的色散特性

摘要

考虑了电磁波在切向磁化铁氧体板中传播的色散特性和磁耗散特性。获得了复杂的（由于耗散）色散关系。发现了仅典型的耗散介质的色散曲线分支。获得了分隔两个明显不同的色散区域的阻尼参数的临界值。结果表明，临界阻尼参数对应于磁振荡从周期性状态到非周期性状态的转变。
