摘要: In this article, the reflection and transmission of plane waves are examined from “negative imaginary” (NIP) “true complex” absorbing potentials (CAP). Comparisons have been made between these two types using our multistep potential method. The results showed that, except for a few cases, CAPs give significantly better values absorption than those given by NIPs. © 2003 Wiley Periodicals, Inc. Int J Quantum Chem,
