The design of multi-layer frequency selective surfaces often requires characterising the behaviour of the structure in wide frequency and angle ranges. Moreover, a fine tuning of the design leads to a large parameter space and results in a long computational time. To address this problem, an efficient parameterisation and interpolation technique has been implemented within the multimode equivalent network approach based on the integral equation formulation, a technique developed for the analysis of multi-layer periodic structures. The paper describes this technique and shows for a test case consisting of an array integrated with an FSS how the calculation time can be drastically reduced.
