由于冷等离子体理论在上部混合谐振附近分解，在弱的无碰撞磁体中的非均匀无碰撞磁体的传播首先在冷等离子体近似中进行了研究。形式基于积分解决方案的不对称扩展，然后推导这些连接公式。在上部混合共振之间，非凡波和静电等离子体波之间的模式转换问题。
The propagation of an extraordinary wave in a weakly inhomogeneous collisionless magnetoplasma is first studied in the cold plasma approximation. As the cold plasma theory breaks down near the upper hybrid resonance, a fourth‐order warm plasma field equation is derived and its solutions obtained in integral form. Connection formulas based on the asymptotic expansion of the integral solutions by the method of saddle‐point integration are deduced. These connection formulas are then applied to the problem of mode conversion between extraordinary waves and electrostatic plasma waves across the upper hybrid resonance.
