Mobile system for microwave removal of concrete surfaces

An applicator for directing microwave energy toward a surface, comprising:

• a waveguide oriented at substantially Brewster's angle with respect to the surface for directing microwave energy at the surface to maximize absorption of the microwave energy by the surface;
• said waveguide having a proximal end with a microwave input and a distal end with an opening permitting exposure of the surface to the microwave energy;
• said waveguide further including arrays of air inlet tubes spaced and dimensioned so as to minimize the escape of microwave energy from said waveguide.

A containment assembly for use with a microwave waveguide for the removal and storage of surface debris dislodged from a surface through the use of microwave energy, comprising:

• a debris collection port coupled to the waveguide, said port also in fluid communication with a storage drum and a vacuum motor,
• said storage drum positioned between said debris collection port and said vacuum motor for the collection of surface debris drawn through said debris collection port, and for the absorption of microwave energy scattered from the surface,
• wherein the scattered microwave energy from the surface is absorbed by surface debris collected in said drum, thereby preventing scattered microwave energy from escaping from said containment assembly.
