METHOD FOR PRODUCING TRAPPING AND TRANSMITTING MEMBRANES

FIELD: materials transmitting or trapping electromagnetic beams of definite wavelength and bandwidth for research and industrial applications. ^ SUBSTANCE: proposed method for producing membranes capable of passing or trapping electromagnetic radiation of definite wavelength lambda and bandwidth Deltalambda to obtain frequency-selective membranes with any composite pattern on any insulating substrate and in any quantity includes coating insulating substrate with low-resistance paste of desired pattern. Used as low-resistance paste is low-viscosity stabilized conducting compound of ultra-dispersed powders, polymeric binder having steady electric conductivity and average particle size of 10 - 600 nm, organic solvent, and surface-active materials, proportion of ingredients being as follows, parts by mass: ultra-dispersed conducting powder, 60 - 90; polymeric binders, 39 - 7; organic solvent, 100 - 400; and surface-active materials, 1 - 3. This compound is applied by means of printer or plotter according to desired program to produce desired pattern whose layer thickness is not smaller than that of skin layer for final procedure, it is dried out. ^ EFFECT: enlarged functional capabilities. ^ 1 cl, 2 tbl
