研究了频率对井下电磁波传输特性的影响，采用金属波导法分析了圆形、拱形及弯曲隧道中电磁波的传输特性并给出衰减率近似公式，得出主要结论：在圆形和拱形隧道中，频率越高，衰减率越小，越有利于电磁波的传播；在弯曲隧道中，频率越高，衰减率越大，不利于电磁波的传播；通过特性曲线与井下实验数据相比较得出在900MHz左右为井下无线通信系统传输信号最佳频段。

Under the control of microprocessor, this product with an oscillating implement embedded in can produce mulriple-scanning pulse electromagnetic wave with variable frequency and mulriple frequency conversion ultrasonic. Electromagnetic wave can get rid of the pests around electrical wire and ultrasonic can dispel the pests in other areas of the room. The product sends out frequency conversion signal of ultrasonic to circumambience. Once touches objects, it reflects and permeates the room. The combining of the two waves has mulriple effects on the central nervous and hearing system of the pests such as rats, cockroachs, spiders and ants. As a result, the pests would be on the rack and agonizing or even have the symptom of swivet and twitch.
