The dielectric properties of a large number of wood samples have been investigated by measuring the complex permittivity as a function of the moisture content. A complex permittivity measurement set up exploiting a coaxial probe has been used. In particular, the reliability of the measurement procedure and repeatability have been verified. Moreover, the moisture content has been determined, according to the standardized practice, evaluating the sample weight change with respect to the anhydrous state. The collected data of the dielectric characteristics of wood have been used for the numeric simulation aimed to investigate the interaction of the electromagnetic field with the exposed sample. More precisely, the electromagnetic and thermal behaviour have been simulated by means of suitable computer code based on the Finite Element Method (FEM).

Abstract
The dielectric properties of a large number of wood samples have been investigated by measuring the complex permittivity as a function of the moisture content. A complex permittivity measurement set up exploiting a coaxial probe has been used. In particular, the reliability of the measurement procedure and repeatability have been verified. Moreover, the moisture content has been determined, according to the standardized practice, evaluating the sample weight change with respect to the anhydrous state. The collected data of the dielectric characteristics of wood have been used for the numeric simulation aimed to investigate the interaction of the electromagnetic field with the exposed sample. More precisely, the electromagnetic and thermal behaviour have been simulated by means of suitable computer code based on the Finite Element Method (FEM).I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
