| ABSTRACT Electromagnetic shielding is one of the most promising applications of superconductors that still needs further investigation. An enhanced model is therefore proposed to design optimum shielding structures made from different low and high criticaltemperature (LTS & HTS) superconductors. The proposed model incorporates classical electrodynamics with both superconductivity macroscopic theories such as two-fluid model, Ginzburg-Landau (GL) theory, and microscopic Bardeen-Cooper-Schrieffer (BCS) theory. Thermodynamic properties are also included using improved Gorter-Casimir relations based on published experimental data. General shielding effectiveness expressions are derived for different superconducting shielding structures against generally polarized incident electromagnetic waves. A computer algorithm is then developed to investigate the impact of superconducting material parameters on shielding effectiveness. The limitations and advantages of superconducting shielding structures are also discussed. | ||||
