海水中的环天线在空气中产生的场

Fields in air due to a loop antenna in sea

海水中的环天线在空气中产生的场受多个参数的影响,针对这个问题,在分析海水中电磁波传播特性的基础上,建立了三层导电媒质(空气、海水、大地)条件下海水中环天线的辐射模型,得到了电磁场的解析表达式,并通过仿真分析了传播频率、海水深度和天线深度对环天线在空气中产生的场的影响,得出了一些有意义的结论,为水下电磁通信的实际应用提供了依据。

The fields in the air generated by the loop antenna in the sea are affected by more than one parameter, aiming at this problem, on the basis of the analysis of the electromagnetic wave propagation characteristics in the sea, the authors establish a radiated model for the underwater loop antenna in three layers of conductive media（air, sea, earth）, and obtain the analytical expressions of the electromagnetic fields. This paper emulates and analyses the influence of the propagation frequency,the depth of the sea and antenna on the fields,and draws some meaningful conclusions,which provides a basis for the application of the underwater electromagnetic communication.
