The dielectric constant of coniferous wood in the frequency range 3-12 GHz

The dielectric properties of softwood (spruce, pine, cedar, f/r) are observed. Measurements were performed /n rectangular resonators in the 3-12 GHz. The comparison with the dielectric constant of birch of different backgrounds, as a representative of deciduous trees, is made. The effect of weight moisture on the dielectric properties of wood was researched. Results can be used for characterization offorest massifs by means of remote sensing techniques.
