ON THE VALIDITY OF BORN APPROXIMATION
2010
Electromagnetic Waves
Born approximation is widely used in (inverse) scattering problems to alleviate the computational difficulty, but its validity and applicability are not well defined. In this paper, a universal criterion to identify the validity of Born approximation is put forward based on applying the operator theory on the scattering integral equation. In comparison with the traditional criteria, the new one excels in its ability to give a wider and more rigorous valid frequency range, especially while
