| Abstract: | The novel concept and procedure of the numerical truncation boundary condition are presented for treating unbounded boundaries in numerical computations of electromagnetic field problems. It is based on postulating the existence of linear equations of the discretized nodal values of the fields that differ from the conventional equations while arriving at the same solutions. Compared with the technique of asymptotic/absorbing boundary condition and the method of measured equation of invariance(MEI), the new approach avoids making a choice of metrons in contrast to MEI which is not invariant to the choice of metrons. Computational precision and efficiency are also gained for simulating complicated open region electromagnetic field problems. |
