Abstract :
For investigation of plane waveguide structures, a circle sector finite element is proposed. Finite element of that form fulfills rand current conditions. Analytical expressions for orthogonal surface currents on such elements are given. Properties of the sector finite element are dependent on the element bent in waveguide cross section. Use of the sector finite element as a noncoordinate waveguide exciter is investigated.
