论文摘要
血浆波的处理通常假设同质性，但是等离子体中无处不在的平行梯度可以改变波浪的传播和吸收。我们通过扩展相关积分并开发出一种新颖的集成技术来得出对任意分布的等离子介电校正的准核不均匀校正，该技术使我们的校正在许多情况下都可以应用于许多情况下，并且比其他不均匀介电公式具有更高的准确性。我们将此介电张量应用于低混合电流的电流驱动问题，并证明不均匀的波浪阻尼不会影响下部Hybrid Wave的线性阻尼条件，并且在非Maxwellian问题中，应保持不变的问题阻尼和传播不变，除非波速度很大。
Treatments of plasma waves usually assume homogeneity, but the parallel gradients ubiquitous in plasmas can modify wave propagation and absorption. We derive a quasilocal inhomogeneous correction to the plasma dielectric for arbitrary distributions by expanding the phase correlation integral and develop a novel integration technique that allows our correction to be applied in many situations and has greater accuracy than other inhomogeneous dielectric formulas found in the literature. We apply this dielectric tensor to the lower-hybrid current drive problem and demonstrate that inhomogeneous wave damping does not affect the lower-hybrid wave's linear damping condition, and in the non-Maxwellian problem damping and propagation should remain unchanged except in the case of waves with very large phase velocities.
