External magnetic field effects on the dispersion properties of hybrid plasmon polariton (HPP) modes are theoretically investigated in a collisional warm magnetized planar conductor–gap–dielectric (CGD) system. This structure consists of a high index dielectric, separated from a warm metallic plasma with a low index nano-sized dielectric layer. The Magnetohydrodynamics model (MHD) coupled to Maxwell’s equations is used to derive the new dispersion relation of HPP waves in the CGD system. Numerical results reveal that the weakly external magnetic field which is parallel to the propagation wave has a significant effect on the dispersion properties of the guide modes and leads to an increase in the surface wave’s confinement and the propagation length of the HPP mode. Also, it is found that the critical gap thickness in the magnetized CGD system is bigger than the critical thickness in the unmagnetized CGD system.

磁化导体间隙介电纳米结构中表面波的理论研究

理论上在碰撞热磁化平面导体-间隙-电介质（CGD）系统中研究了外部磁场对混合等离子体激元极化（HPP）模式的色散特性的影响。该结构由高折射率电介质组成，该电介质与具有低折射率纳米尺寸电介质层的温暖的金属等离子体隔开。磁流体动力学模型（MHD）与麦克斯韦方程组耦合，用于推导CGD系统中HPP波的新色散关系。数值结果表明，与传播波平行的弱外部磁场对波导模式的色散特性有显着影响，并导致表面波的限制和HPP模式的传播长度增加。也，
