等离子体中的表面凹槽波：本征波、激发和应用

这本书提出了一个全面的理论研究电磁本征波传播垂直于对称轴在各种圆柱波导结构填充磁激活等离子体。这是我们2014年出版的《等离子体中的表面长笛波理论与应用》一书的第二版，更新版和显著扩展版，该书发表在《原子、光学和等离子体物理斯普林格系列》上。首先，本文还对波能量绕波导轴线的旋转进行了研究。其次，详细研究了电子束绕轴旋转对这些波的激发。“表面波”是指这些波只沿等离子体表面传播，而不是在均匀的无限等离子体中传播。它们的波幅随着离开等离子体边界进入等离子体深度而减小。“长笛”是指假设等离子体柱中波的轴向波数kz为零，波只在方位方向传播。在这种情况下，密度恒定的表面类似于有凹槽的希腊柱。然而，小而有限kz的存在可以通过使用表面凹槽波理论作为第零方法的逐次近似方法来考虑。文中还介绍了表面波目前的各种应用和未来可能的应用。
Surface Flute Waves in Plasmas: Eigenwaves, Excitation, and Applications
This book presents a comprehensive theoretical study of the electromagnetic eigenwaves propagating perpendicular to the axis of symmetry in various cylindrical waveguide-structures filled with magneto-active plasma. It is the second, updated and significantly expanded edition of our book “Surface Flute Waves in Plasmas. Theory and Applications”, published in 2014 in the “Springer Series on Atomic, Optical, and Plasma Physics”. First, the text is complemented by a study of the wave energy rotation around the axis of the waveguides. Second, excitation of these waves by an electron beam gyrating around the axis is investigated in detail. “Surface waves” means that these waves only propagate along plasma surfaces and not in uniform infinite plasmas. Their wave amplitudes decrease with going away from the plasma boundary into the plasma depth. “Flute” means that the axial wavenumbers kz of the waves in plasma cylinders are assumed to be zero, and the waves only propagate in azimuthal direction. In this case, the surfaces of constant density resemble fluted Greek columns. However, the presence of a small but finite kz can be taken into account by the method of successive approximations, using the theory of surface flute waves as zeroth approach. A variety of present applications of surface waves and possible future applications are also included.
