Abstract: Different from traditional numerical methods, the theory of Maxwellian circuits (MC) combines the field theory and the circuit theory, providing a perfect connection of the two. In this paper, square loop scatterers are analyzed with MC. The methods of solving square loop scatterer and broadband characteristics of MC are investigated, and current distributions obtained. Numerical results show that the solutions are the same as those obtained with the method of moments (MoM). It has been found that MC can provide solutions over a quite wide range of frequencies, which is more efficient and practicable than other numerical methods.
