[0056] In a second aspect, the present invention provides a method for preparing the multi-spectral transparent microwave absorbing material provided in the first aspect of the present invention, the preparation method comprising the following steps:
[0057] (1) a step of plating a surface layer periodic metal grid on the upper surface of the optical window by photolithography; and
[0058] (2) A step of plating the underlying periodic metal grid on the lower surface of the optical window by using a photolithography process.
[0059] It should be noted that the change in the order of step (1) and step (2) will not affect the preparation method.
[0060] In some preferred embodiments, the step (1) is carried out as follows:
[0061] Coating photosensitive adhesive on the surface of the optical window, using a mask plate prefabricated according to the pattern of the periodic metal grid on the surface for pattern exposure, and then developing, and then using vacuum magnetron sput...
