Annotation: In the research we developed the theoretical model of light beam diffraction on the holographic photonic structures formed in polymer-dispersed liquid crystal (PDLC), under the influence of the discrete spatially inhomogeneous electric field. A numerical simulation of diffraction characteristics under the action of an external control field, with the different electr ode structure topology on the surface of the sample is performed in the fixedfield approximation. A new apodization method of hologra phic photonic PDLC structures is shown based on the simulation results
