Abstract
A microwave energy trap for use in conjunction with the exit and entrance ports of a conveyorized microwave oven. The energy trap operates to prevent the escape of microwave energy through the ports into the surrounding environment. The energy trap comprises a tunnel having a current suppressing coating, resonant slots communicating through the wall of the tunnel, and waveguide chambers located over the slots for absorbing and dissipating microwave energy.
