  Exceptional Field Theory employs an extended spacetime to make supergravity
fully covariant under the U-duality groups of M-theory. This allows for the
wave and monopole solutions to be combined into a single solution which obeys a
twisted self-duality relation. All fundamental, solitonic and Dirichlet branes
of ten- and eleven-dimensonal supergravity may be extracted from this single
solution in Exceptional Field Theory.
