Embodiment Construction
[0031] The present invention will be further described below in conjunction with accompanying drawing.
[0032] Such as figure 1 As shown, the steps of the method for making the curved surface FSS by the three-dimensional printing technology of the specific embodiment of the present invention are:
[0033] (1) Surface FSS simulation design: establish the surface FSS and its compound wall model in the professional electromagnetic simulation software;
[0034] Considering FSS's resonant bandwidth, angular stability, anti-cross-polarization characteristics, surface quasi-periodic characteristics and other response characteristics and the difficulty of processing, the Y-shaped array is an ideal structural unit for radome, so this The FSS design of the embodiment selects the Y-shaped unit, but structural units such as cross, square, circle and ring can also implement the present invention;
[0035] In the established model, accurately input the electrical parameters of each layer...
