I hope that this text sheds a new light on some aspects of the Driac theory which to my knowledge have not yet found their way into textbooks, for example, a rigorous treatment of the nonrelativistic limit, the supersymmetric solution of the Coulomb problem and the effect of an anomalous magnetic moment, the asymptotic analysis of relativistic observables on scattering states, some results on magnetic fields, or the super symmetric derivation of solutions of the mKdV equation.

After a careful solution of the movement equation of particles as well as the Klein-Gorden equation in curved space-time, and the analgesic continuation of out going wave in the complex number r plane, it reaches a conclusion that the radiation spectrum of black hole is rigorous black body radiation spectrum.

However, the response spectrum analysis method advanced in this paper is an important contribution, because time-history analysis has to carry through before even for the relatively rigorous and complete solution of linear structures.

The shape of the staff's section affect the RCS strongly. As a basic research work for electromagnetic scattering of 2D complex target, this disseration provides the powerful way in rigorous modeling and effective solution. The informations given in the disseration can help the stealth technology of aircraft.
