Abstract :
The basic idea of the measured equation of invariance (MEI) is that a relationship can be found for the scattered field at the boundary. The boundary conditions are found from several measuring functions called metrons. To improve the MEI solution, we must develop a systematic manner for choosing the metrons. In this paper, three approaches are presented for producing an accurate boundary condition.
