 In this paper, the nature of the orientational properties of thephysical magnitudes is revealed through the rotation of the coordina-te frames. The geometrical model of the second order tensors is con-structed by a surface area vector do combined with a inclined actionvector df, and a general method of building a geometrical model ofthe tensor is derived from the scalar product of a tensor and a vectora on the right of it. An example of analysing an applicable physicalproblem by using this method is also presented....

The RWG basis function and triangular basis function are chosen to discretizated the conduting ground plane and thin wire, respectively, and a special basis function is used to represent the current on the wire/ground-plane junctions. The numerical resuluts of two practical sleeve antennas located respectively at circular and square ground plane are compared with the measured data to prove validity...
