Study on the Surface Fractral to the Microwave Absorbing Properties of the Microwave Absorbing Ceramic Compound Material

By RCS measurement system.microwave absorbing properties of the microwave absorbing ceramic compound material were studied.as well as its surface properties.The results showed the surfaces of the materi- al used had the fractral properties and their fractal dimensions were 2.3602.2.3907 and 2.6255 respectively, the relative reflectivity appeared linear relativity to the frequency emitted.the relative reflectivity of the material with different surface properties got different increasing speed when frequency increasing and the increasing speed(slope)of the relative reflectivity of the microwave absorbing ceramic material appeared remarkable linear relativity to its fractal dimension.
