摘要
将微扰法用于电磁波领域 ,把影响常态的参数、边界条件等变化量作为微扰 ,把未变化前的场态作为近似基态 ,通过理论推导得到了由于介质变化而引起的谐振频率变化的精确解析式 。
Based on the micro-disturbance method,the parameters and the boundary conditions related to the constant state of the electric-magnetic field are introduced as the micro-disturbance and the field state before variation as the approximation of the base state,the accurate analytic expression on the variation of resonant frequency with the variation of medium parameters has been derived.Its accuracy and effectiveness have been demonstrated by some examples.
