Begun in 1973, the Review of Progress in Quantitative Nondestructive Evaluation (QNDE) is the premier international NDE meeting designed to provide an interface between research and early engineering through the presentation of current ideas and results focused on facilitating a rapid transfer to engineering development.
This site provides free, public access to papers presented at the annual QNDE conference between 1983 and 1999, and abstracts for papers presented at the conference since 2001.

Abstract
The T-matrix method (TMM) and the Helmholtz integral equation method (HIEM) are wave scattering formalisms for irregularly shaped targets. They are both based on the Helmholtz integral formula (HIF) but they use different ways to achieve the discretization required for numerical evaluation.
