Description
Summary:This paper deals with the characterization of ohmic losses induced by galvanized steel in diffuse field environments. It is then used to compute the mean response of electrically large resonant structures using a statistical method called "Power Balance" (PWB). The ohmic losses are often predominant and thus need to be properly modelled for the method to be accurate. It is especially true for galvanized steel, as it induces losses several orders of magnitude greater than those of untreated steel. First, this paper reviews the principle of the method before presenting a new empirical method for evaluating ohmic losses induced by coated metals such as galvanized steel. Finally, this method is used as a tool to create an accurate PWB model of a six-cavity configuration, validated by measurements.
