Abstract
Apparatus and methods are described for excavating earthen material with millimeter-wave (MMW) radiation or a combination of MMW radiation and mechanical apparatus. The MMW radiation can reduce costs and hazards associated with excavation using mechanical means only and/or explosives. MMW-assisted excavation has significant energy advantages over optical or long-wavelength microwave excavation techniques.
