Effects of Seasonal Growth Rings on the Microwave Measurement of Wood
Abstract
In order to determine more accurate indicators of wood structure obtained by microwave sensing and improve our understanding of plane wave propagation through this complex material, we have undertaken a permittivity survey and experimentally investigated scattering of a plane wave, measuring its transmission over two non-parallel surfaces of a rectangular lumber sample. This novel non-destructive testing techn-ique offers results which may significantly contribute in a more accurate propagation modeling and industrial wood quality testing.
