In a process for producing microstructure components on a substrate which carries electronic microcircuits cooperating functionally with the microstructure components, a first layer of a plastic material which connects with the substrate is applied to the substrate and a second layer of a plastic material which includes a separating agent but which firmly connects with the first layer is applied to the first layer and a molding tool is then impressed into the second layer to form the desired microstructures or to form cavities into the plastic material, which, upon removal of the molding tool, are filled with a metal to form the desired microstructures on the substrate upon removal of the plastic material.

In a band-pass filter for electromagnetic radiation comprising a membrane having periodically arranged slot structure elements formed therein each consisting of at least three slots of equal length extending from a common point in radial symmetry, the membrane with the slot elements has a thickness of 33 to 500 .mu.m and the ratio of the membrane thickness to the grating constant which defines the periodic arrangement of the slot structure elements is larger than 1, thereby achieving optimum blocking characteristics for the filter.
