We present 2D and 3D vector absorbing boundary conditions for unbounded microwave problems. Coupling with vector formulation leads to a non-symmetric system matrix. We show how it is possible to symmetrise these conditions with the same degree of precision, Edge and corner conditions are also presented for rectangular boundaries.
