论文摘要
提出了一种在30 MHz频段中运行的便携式无线电通信系统，并能够传输高清现场水下视频图像。系统操作基于使用特殊设计的表面波天线沿沿水界面传播的电磁表面波。由于表面电磁波的传播长度远远超过了相同频率的散装无线电波的皮肤深度，因此该技术可用于在几米距离内的视频水下通信。同样，该系统似乎在通过水上界面进行通信效率很高。
A portable radio communication system operating in the 30 MHz band and capable of transmitting high-definition live underwater video images is presented. The system operation is based on launching electromagnetic surface waves propagating along water-air interface using specially designed surface wave antennas. Since the propagation length of the surface electromagnetic waves far exceeds the skin depth of bulk radio waves at the same frequency, this technique is useful for video communication underwater over distances of several meters. Also, this system appears to be efficient at communicating through the water-air interface.
