The field of microwave tubes is very old and it is improbable to find new principles. On the other hand, new fabricational technologies have become available and the push to higher frequencies is ever increasing. This may open avenues to realize new devices which were not possible before. The proposal aims for investigating trajectory-modulated or deflection-modulated devices in the range of 30 - 100 GHz. It is expected, that the linearity is better than in existing devices due to reduced spacecharge effects, and that the efficiency of a depressed collector is higher in case of monoenergetic beams. In particular, planar devices should be studied which are well suited for new technologies like deep x-ray lithography (LIGA) and wire electro-discharge-machining (EDM). As an example, a planar oscillator tube should be modeled and simulated. Here a continuous beam passes through a cavity resonator and will be energy modulated. In a following dipole magnet the beam is bent by 180° and performs transverse displacement oscillations. The backward traveling beam passes the same cavity at a different transverse position with a voltage node and pumps energy into the cavity. The field in the cavity builds up from noise until it reaches saturation.

微波管领域非常古老，不太可能找到新的原理。另一方面，新的制造技术已经变得可用，并且对更高频率的推动正在不断增加。这可能为实现以前不可能实现的新设备开辟途径。该提案旨在研究30 - 100 GHz范围内的磁阻调制或偏转调制设备。可以预期的是，由于减少了空间电荷效应，线性度比现有设备更好，并且在单能束的情况下，凹陷的收集器的效率更高。特别是，应该研究平面器件，这是非常适合的新技术，如深X射线光刻（LIGA）和线放电加工（EDM）。作为一个例子，平面振荡管应建模和仿真。这里，连续光束通过空腔谐振器并且将被能量调制。在随后的偶极磁体中，束被弯曲180°并执行横向位移振荡。后向传播的光束在具有电压节点的不同横向位置处通过相同的腔，并将能量泵入腔中。空腔中的场由噪声建立，直到达到饱和。
