of each other or connected by means of adhesive layers in any combination of these means of assembly alternatively to the method described above it is possible to prepare the qwf and hwf from a readily synthesized liquid crystal lc polymer that is applied onto a substrate for example at a temperature above its glass transition temperature or its melting point or from solution e g in an organic solvent aligned into planar orientation and solidified e g by evaporating the solvent or by cooling below the glass temperature or melting point of the lc polymer if for example a lc polymer with a glass temperature that is higher than ambient temperature is used evaporation of the solvent or cooling leaves a solid lc polymer film if for example an lc polymer with a high melting point is used the lc polymer can be applied as a melt onto the substrate which solidifies upon cooling lc side chain polymers or lc main chain polymers can be used preferably lc side chain polymers the lc polymer should preferably be selected such that its glass transition or melting temperature is significantly higher than the operating tempature of the aqwf for example lc side.
