具有阻抗边界条件的波导中的模式和例外点

Modes and exceptional points in waveguides with impedance boundary conditions

Bikashkali Midya, Vladimir V. Konotop

摘要:

考虑了由非理想金属板构成的具有阻抗边界的平面波导,其中填充有有源或无源介质。我们展示了在介质中加入均匀泵浦时选择性导模和放大的可能性,并分析了TE模和TM模传播的差异。这样一个非保守的系统也示出功能例外点,为特定的和实验可调参数,这是一个特定的透明电介质的情况下描述。

英文摘要:

A planar waveguide with impedance boundary, composed of non-perfect metallic plates, and with passive or active dielectric filling is considered. We show the possibility of selective mode guiding and amplification when homogeneous pump is added to the dielectric, and analyze differences in TE and TM mode propagation. Such a non-conservative system is also shown to feature exceptional points, for specific and experimentally tunable parameters, which are described for a particular case of transparent dielectric.
