本文对已有的磁控管模拟单波长移动码（DEMAG）进行了多波长扩展（MWMAG），并对4J52 X波段磁控管进行了模拟。多波长代码模拟磁控管中的所有波长，消除了单波长代码中所有波长相同的可疑假设。总功率，效率，和耗散的结果，使用多波长代码是接近使用单波长代码获得的。然而，相互作用的细节却有很大的不同，特别是当二次发射占主导地位时，就像大多数磁控管的情况一样。在这种情况下，存在以穿过空间电荷的空隙的形式的扰动，其具有与射频波长不同的波长。
A multiple wavelength extension (MWMAG) of a prior single moving wavelength code for the simulation of magnetrons (DEMAG) has been prepared and used to examine the operation of the 4J52 X-band magnetron. The multiple wavelength code simulates all of the wavelengths in the magnetron, eliminating the questionable assumption in the single wavelength code that all wavelengths are identical. The gross power, efficiency, and dissipation results obtained using the multiple wavelength code are close to those obtained using the single wavelength code. Details of the interaction are, however, significantly different-particularly when secondary emission is dominant as is the case in most magnetrons. In this case, there is a disturbance in the form of voids traveling through the space charge, which have a wavelength which is different from the radio frequency wavelength.
