Shielded Waveguide, reason is the wide application of modern guiding systems such as microstrip and slot transmission lines, which produces new types of problems to be solved numerically and requires elaborating specific methods of the spectral theory of (OVFs) and (OPs).GONG 发表于 2025-3-25 08:00:24

Open Waveguides of Arbitrary Cross Section, hollow shielded waveguides (filled with homogeneous dielectric) the spectral parameter enters the equations and not the transmission conditions, ending up with an eigenvalue problem for a self-adjoint operator. However, a general setting for a metal-dielectric waveguide yields non-self-adjoint bounCultivate 发表于 2025-3-25 20:50:06
Conclusion, of arbitrary cross section (including the shielded ones). The settings for the Maxwell are reduced to boundary eigenvalue problems for the longitudinal components of the electromagnetic field in Sobolev spaces using a universal approach applicable to all the considered waveguide families.
