摘要

我们考虑了径向偶极子对均匀介质球的电磁振荡的激励，这些振荡形成了一个周期性的无线电脉冲序列。研究表明，在高频下，场分布接近于与这些频率对应的本征振荡的场分布，而相邻谐波在低频下也有影响。还表明，为了激励谐振器中的短无线电脉冲，需要以低Q因子为特征的低频下的动作。

Excitation of Electromagnetic Oscillations of a Dielectric Ball by a Complex Oscillation of a Radial Dipole

We consider excitation of electromagnetic oscillations of a homogeneous dielectric ball by a radial dipole, oscillations forming a periodic sequence of radio pulses. It is shown that at high frequencies the field distribution is close to the field distribution of the eigenoscillations corresponding to these frequencies, whereas the neighboring harmonics also have an impact at low frequencies. It is also shown that an action at low frequencies characterized by a low Q-factor is needed for exciting short radio pulses in the resonator.
