Abstract : The fabrication of microwave absorbing materials requires the ability to make materials with well-controlled properties such as shape, thickness, permittivity and permeability. The ability to measure the permittivity and permeability is an essential requirement for designing an optimised absorber. And good optimisations codes are required in order to achieve the best possible absorber designs. In this report, the results from a Technology Investment Funded project on the fabrication of organic radar absorbing materials are presented. The absorbing phase used was based in conducting polymers, which were synthesised and characterised for control and correlation of absorptive properties. The materials made were characterised through measurement of their conductivity and permittivity at microwave frequencies. Methods were then developed for optimising the design of microwave absorbers. A porotion of the TIF also focussed on the development of radar cross section modelling software with the capability of determining the radar cross section of a platform with absorbing patches applied.
