Generalized coupled mode formalism in reciprocal waveguides with gain/loss, anisotropy or bianisotropy
Weijin Chen, Zhongfei Xiong, Jing Xu +1
In anisotropic or bianisotropic waveguides, the standard coupled mode theory fails due to the broken link between the forward and backward propagating modes, which together form th…

We study the decay of gap plasmons localized between a scanning tunneling microscope tip and metal substrate, excited by inelastic tunneling electrons. The overall excited energy f…
General coupled mode theory in non-Hermitian waveguides
Jing Xu, Yuntian Chen
In the presence of loss and gain, the coupled mode equation on describing the mode hybridization of various waveguides or cavities, or cavities coupled to waveguides becomes intrin…
Elimination of polarization degeneracy in circularly symmetric bianisotropic waveguides: a decoupled case
Jing Xu, Bingbing Wu, Yuntian Chen
Mode properties of circularly symmetric waveguides with one special type of bianisotropy are studied using finite element approach. We find that the polarization degeneracy in circ…
