摘要:

本文报道了在空心圆柱介质腔中观察到的布喇格限制模。在13.4 $GHz$处观察到谐振,其具有$2\times10^5$级的无载Q因子,其比介电损耗极限高6倍以上。以前,这种模式仅从没有方位角变化且仅具有$E_ϕ$分量的纯横电模式实现。从严格的数值模拟结果表明,该模式是一个混合模式与非零的方位角变化,并与占主导地位的$E_r$和$E_ϕ$电场分量和$H_z$磁场分量。

英文摘要:

The authors report on observation of Bragg confined mode in a hollow cylindrical dielectric cavity. A resonance was observed at 13.4 $GHz$ with an unloaded Q-factor of order $2\times10^5$, which is more than a factor of 6 above the dielectric loss limit. Previously such modes have only been realized from pure Transverse Electric modes with no azimuthal variations and only the $E_ϕ$ component. From rigorous numeric simulations it is shown that the mode is a hybrid mode with non-zero azimuthal variations and with dominant $E_r$ and $E_ϕ$ electric field components and $H_z$ magnetic field component.
