Abstract
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.Keywords
