| Abstract: |
| Objective To investigate the effect of the stacking type and volume fraction of the metal dipoles on the dielectric properties of the metal dipole arrays/plastics composites in X-band. Methods The laser carving technique was used to fabricate the sheets with two-dimensionally periodical arrays of metal dipoles (with the size of 1 mm×0.05 mm). The sheets were stacked with three different types to render the metal dipole arrays/plastics composites. The effective complex permittivities (both ε' and ε") of the composites were tested by Network Analyzer. The distribution of the electric field on dipoles was simulated by the ansoft HFSS software. Results It was shown that the value of ε′ of the composites increased with the rising volume fraction of the metal dipoles, and could be adjusted in the range from 3~83 by the volume fraction of the metal dipoles and the stacking type; and that ε" of the composites was maintained at very low values-mostly less than 4 in this large variation range of ε'. Conclusion Depending on the specific requirement of a practical application, a kind of materials with adjustable ε' simultaneously keeping low values of ε" can be designed. |
