Abstract

Recently, the realization of electromagnetic wave signal transmission and reception has been achieved through the utilization of the magnetoelectric effect, enabling the development of compact and portable low-frequency communication systems. In this paper, we present a miniaturized low-frequency communication system including a transmitter device and a receiver device, which operates at a frequency of 44.75 kHz, and the bandwidth is 1.1 kHz. The transmitter device employs a Terfenol-D (80 mm × 10 mm × 0.2 mm)/PZT (30 mm × 10 mm × 0.2 mm)/Terfenol-D glued composite heterojunction magnetoelectric antenna and the strongest radiation in the length direction, while the receiver device utilizes a manually crafted coil maximum size of 82 mm, yielding a minimum induced electromagnetic field of 1 pT at 44.75 kHz. With an input voltage of 150 V, the system effectively communicates over a distance of 16 m in air and achieves reception of electromagnetic wave signals within 1 m in simulated seawater with a salinity level of 35% at 25 °C. The miniaturized low-frequency communication system possesses wireless transmission capabilities, a compact size, and a rapid response, rendering it suitable for applications in mining communication, underwater communication, underwater wireless energy transmission, and underwater wireless sensor networks.

摘要

最近，通过利用磁电效应实现了电磁波信号的发射和接收，从而推动了紧凑便携的低频通信系统的发展。在本文中，我们展示了一种小型低频通信系统，它包括一个发射装置和一个接收装置，工作频率为44.75kHz，带宽为1.1kHz。发射装置采用了一种由Terfenol-D（80mm×10mm×0.2mm）/PZT（30mm×10mm×0.2mm）/Terfenol-D胶合而成的复合异质结磁电天线，其在长度方向上辐射最强，而接收装置则使用了一个手工制作的最大尺寸为82mm的线圈，在44.75kHz时产生的最小感应电磁场为1pT。在输入电压为150V的情况下，该系统在空气中能有效通信16m的距离，并且在25°C、盐度为35%的模拟海水中能在1m范围内接收到电磁波信号。这种小型低频通信系统具有无线传输能力、紧凑的尺寸和快速的响应，适用于采矿通信、水下通信、水下无线能量传输和水下无线传感器网络等应用。
