NEW ALGORITHM FOR OPTIMAL DIELECTRIC MATERIAL SELECTION IN MARINE ENVIRONMENT

The materials’ selection demands knowledge from different disciplines, depending on application. Very important parameters that influence dielectric material's properties in, for example, marine applications are operating frequency, expected temperature in practice and moisture. The proposed optimal solution for the dielectrics choice is based on theory of sets. Instead of using function to find best value for the dielectric constant, the parameters’ dependences are used to produce sets of possible values, which are used to find the optimal material for the desired application. The intersection of the three sets of possible solution is the optimal solution if the material with such value exists. If not, maximum acceptable deviation is used to find the acceptable material.
