Unveiling the diverse applications and problem-solving capabilities of the MOM-GEC hybrid approach: a comprehensive systematic review

Hybrid numerical methods show great potential in enhancing conventional approaches, particularly when dealing with complex structures beyond the capabilities of individual methods or standard software. This paper provides a comprehensive overview of the Method of Moments combined with the Generalized Equivalent Circuit (MOM-GEC) in electromagnetic modeling. Through comparative analysis with traditional numerical methods such as the Method of Moments, Finite Difference Time Domain (FDTD), and Finite Element Method (FEM), MOM-GEC’s unique advantages in adaptability, accuracy, and computational efficiency are highlighted. Mathematical formulations based on equations are integrated to clarify the method’s concepts and integration processes. The study showcases MOM-GEC’s successful deployment in various applications, demonstrating its versatility and efficacy in intricate scenarios such as antenna arrays, graphene-based metamaterial devices, and dosimetry in partially enclosed environments. Each case study undergoes re-evaluation by incorporating the generalized equivalent circuit approach, emphasizing MOM-GEC’s effectiveness in addressing diverse challenges. This underscores MOM-GEC’s versatility and efficacy across complex scenarios, reaffirming its value in electromagnetic modeling.
