Abstract

The direct current injection (DCI) method, sometimes also referred to as direct drive, for aircraft high-intensity radiated field (HIRF) certification is evaluated. The method aims at reducing the necessity of resource-intensive radiated field testing at frequencies below the very high frequency band. Surface currents of a fuselage model are evaluated both analytically for incident fields and using DCI techniques. Resulting conductor currents occurring inside the fuselage model are measured and compared for both the incident field and DCI measurement techniques. The comparison approach is a direct one, meaning that no transfer function is applied between the methods.
