Description
Summary:In order to solve the problem on designing scale model for microwave transmitting composites, an effective method has been proposed in this manuscript based on the transmission and reflection (TR) coefficients. By optimizing parameters including the number of layers, the thickness and the electromagnetic parameters of each layer, the TR coefficients of designed scale material could be identical with that of the theoretical scale composite. An example is given according to the proposed method by optimizing the TR coefficients as well as only the reflection coefficient and two designed scale materials are obtained. A combined model of a transmitting hemisphere shell and a PEC paraboloid is constructed to verify the validation of the designed scale materials. FEKO is employed to simulate the monostatic radar cross section (RCS) and comparison is performed between the theoretical scale model and the designed scale models. Result reveals that the model including the designed scale material by optimizing the TR coefficients is more consistent with the theoretical scale model than that including the designed scale material by only optimizing the reflection coefficient. This work has important theoretical and practical significance in electromagnetic measurement.
