研究目的
To analyze electromagnetic wave propagation in a superconducting parallel-plate waveguide filled with an indefinite medium and derive the dispersion relations of transverse electric and transverse magnetic wave modes using the Meissner boundary conditions.
研究成果
The study demonstrates significant effects of the anisotropy of the indefinite medium and the presence of HTS plates on the dispersion characteristics of the waveguide structure. The results are useful for designing new types of parallel-plate waveguide devices operating at microwave frequencies.
研究不足
The study is theoretical and does not involve experimental validation. The analysis is limited to simple geometrical configurations of the waveguide structure.
1：Experimental Design and Method Selection:
The study involves theoretical analysis of electromagnetic wave propagation in a superconducting parallel-plate waveguide filled with an indefinite medium. The Meissner boundary conditions are employed to derive the dispersion relations for TE and TM wave modes.
2：Sample Selection and Data Sources:
The waveguide structure consists of two high-temperature superconducting (HTS) parallel plates separated by a distance 'a' and filled with an indefinite medium.
3：List of Experimental Equipment and Materials:
The study is theoretical and does not involve physical experiments or equipment.
4：Experimental Procedures and Operational Workflow:
The analysis involves solving Maxwell’s equations for the anisotropic indefinite medium and applying the Meissner boundary conditions to derive the dispersion relations for TE and TM waves.
5：Data Analysis Methods:
Numerical analysis of the dispersion relations is performed by plotting the phase velocity versus propagation frequency to identify regions of propagation/non-propagation.
