A new method is introduced for imaging of the standing-wave patterns inside superconducting tunnel junctions coupled to an external microwave source. The method is based on electron-beam scanning of the tunnel junctions using the concept of low-temperature scanning electron microscopy. For two different junction geometries, results are shown which confirm the established models for the propagation of microwaves inside superconducting tunnel junctions.
