Wood timber disinfestation by microwave power application

Different durations to treat bulk timbers have been assessed. The investigation is based on wood timber samples, woodworm larvae and a circular antenna prototype. The research establishes an initial treatment duration, measures the temperature at such duration and estimates durations and extermination rates at different depths. The current results demonstrate that he heating is more homogeneous in overlapped radiation and the treatment duration is strongly related to timber thickness or treatment depth. The treatment duration ranged from 20 to 50 seconds depending on application method and the applied power.
