Abstract
This article presents and validates a new truncation condition that is capable of absorbing all higher-order modes. This new truncation condition that we refer to as a Floquet ABC involves infinite series that need to be truncated for practical use, and a few terms in the infinite series are often sufficient to obtain very accurate results
