Abstract
- The electromagnetic field behind buildings is calculated by making us! of the equivalence principle in two-dimensional environments. We derive equivalent currents on the building walls and other boundaries. The electromagnetic field at a receiver behind the building is calculated from those currents. We also visualize the Poynting vector field strength behind the building, which makes clear how the field is reflected or diffracted around the top of the building. We compare our result with a knife-edge model and a ray-tracing model, and we confirm that the equivalence principle provides predictions of the fields accurately. The calculation method is applied to multiple buildings by using it consecutively to obtain the field behind the last building. [ABSTRACT FROM AUTHOR]
