Modeling Method for Curved Surface of Frequency Selective Surface

This paper proposes a modeling method for Frequency Selective Surface (FSS) units on curved surfaces. By fine-tuning the shape of FSS units on the unfolded surface, precise arrangement on surface is achieved, avoid residual subarraying. This design not only enables a more complete layout of the array in the overall structure but also demonstrates excellent electromagnetic performance. It addresses limitations in traditional design methods for arranging on curved surfaces and improves the overall stealth performance.
