Abstract

Metallized, particularly nickel-coated, knitted net fabrics are suitable for protecting the eyes against microwave radiation with very little adverse effect upon the field of vision, particularly when the mesh width of the knitted net fabrics amounts to <0.25 .lambda., preferably <0.1 .lambda., .lambda. being the wavelength of the radiation to be screened off at the upper frequency limit.
