Example Sentences

For modes in which the electric field is maximum at the patch edges, the patch can be equivalently described as having a magnetic surface current density, KM, that flows along the periphery of the patch, with magnitude given by 2E ×n, where the field is determined at the patch edge and is a unit vector normal to the surface.
