A stable implementation of multiple Higdon’s absorbing boundary condition for Maxwell’s equations
1) This letter presents a stable implementation of Higdon’s ABC at multiple layers without attenuation factor.
2) The multiple Higdon’s ABC works well with wide-band frequency and ultra-thin layers, such as three.
3) Optimal parameters of the multiple Higdon’s ABC are presented in this letter.
4) The optimal angels of the multiple Higdon’s ABC satisfy a circle equation.
