便携式微波灭虫器的结构可分为两大部分,角锥喇叭天线和磁控管合为一个部分,而电源及其控制电路为另一部分,其间用软线连接。由移动式的辐射天线照射生物体,以达到灭虫作用。喇叭天线分为:H面扇形、E面扇形、角锥喇叭及圆锥形喇叭四种。圆锥形喇叭天线场的分布与圆波导相同,并且实用价值极小。严格求解喇叭天线的口面场相当困难,通常是采用近似法。H面扇形喇叭和E面扇形喇叭一般天线书都作了详细的论述。角锥形喇叭由于理论上的困难,其口径场还没有详细、精确的解,其原因就是角锥喇叭的内表面不能与任何坐标系的坐标面重合,从而很难用边界条件来确定电磁场微分方程的积分常数,
Portable microwave insect pest control structure can be divided into two parts, pyramid horn antenna and magnetron together as a part, and the power supply and its control circuit for the other part of the connection with a soft line. By the mobile radiation antenna illuminate organisms, in order to achieve pest control. Horn antenna is divided into: H fan sector, E fan sector, pyramid horn and cone speaker four. Conical horn antenna field distribution and circular waveguide the same, and the practical value is minimal. Strict solution to the horn antenna port field is quite difficult, usually using approximation. H-sector fan-shaped speakers and fan sector E antenna generally made a detailed discussion of the book. Due to the theoretical difficulties, the pyramid horn has no detailed and exact solution of the caliper field. The reason is that the inner surface of the pyramid horn can not coincide with the coordinate surface of any coordinate system, so that it is very difficult to determine the electromagnetic field differential The integral constant of the equation,
