【摘要】 本文基于永磁体式机械天线的辐射机理研究了其发射的低频电磁波在空气-冰层-海水-海床中的跨介质传播特性。通过磁偶极子等效永磁体式机械天线在空间中辐射电磁场的模型,并耦合空气-冰层-海水-海床介质中低频电磁波传播模型,明晰永磁体式机械天线在空气介质中发射的电磁波跨冰层的传播规律。再利用仿真研究了永磁体式机械天线在跨冰层界面时磁场和电场的变化。更多还原

【Abstract】 This paper investigates the propagation characteristics of low-frequency electromagnetic waves emitted by a permanent magnet type mechanical antenna in air-ice and seawater based on its radiation mechanism.A model of the electromagnetic field radiated by a magnetic dipole-equivalent permanent magnet mechanical antenna in space is coupled with a model of the propagation of low-frequency electromagnetic waves in air-ice-seawater media to clarify the propagation law of electromagnetic waves emitted by a permanent magnet mechanical antenna in air media across the ice layer.Simulations are then used to study the variation of the magnetic and electric fields of the permanent magnet mechanical antenna across the ice interface.更多还原
