“…Radiation area of 2.45 GHz magnetron is 3.2 times more than 5.8 GHz magnetron. Assuming that heating spot occupies the same ratio of horn caliber, power density of asphalt mixture surface will increase 4.3 times using 5.8 GHz magnetron in theory [22][23][24][25][26][27]. (2) The power density of asphalt mixture surface heating by 5.8 GHz magnetron is 4.8 times more than heating by 2.45 GHz magnetron.…”

The paper puts forward microwave deicing after analyzing the shortage of deicing using chemistry, thermal and mechanism. It points out that study of microwave deicing is restricted by deicing efficiency. In order to improve the microwave deicing efficiency and achieve fast deicing in winter road maintenance, the influence factors of microwave deicing efficiency are studied. Then frequency of microwave is simulated by CST software. The findings indicated that deicing efficiency is concerned with the microwave frequency, electric field intensity of microwave, road material, environmental temperature, thickness of ice, impurity content of ice, heating mode of microwave, distance between road and waveguide mouth and so on. At the same condition, the deicing efficiency of 5.8 GHz magnetron is four times more than 2.45 GHz magnetron.

“…The advantage of the boundary diffraction wave theory is based on the line integral reduction in the surface integrals. For the problems with complex geometries, the evaluation of the surface integrals needs high computation times [17]. However, it is well known that the surface of the scatterer contributes to the geometrical optics waves, which can be easily evaluated by taking into account the classical method of geometrical optics.…”

In this paper, the uniform scattered fields from a perfectly conducting (PEC) half plane are studied with the extended theory of the boundary diffraction wave. A new vector potential of the boundary diffraction wave is found by considering the Fermat principle for the PEC surfaces. This vector potential is applied to the Helmholtz-Kirchhoff integral, and the theory of the boundary diffraction wave is extended to the PEC surfaces. The extended theory of the boundary diffraction wave is then applied to the scattering problem for the PEC half plane. The total scattered fields are compared numerically with the exact solution for the same problem. The numerical comparisons given in the paper show that the solution of the extended theory of the boundary diffraction wave is very close to the exact solution.

Abstract-A new mathematical method and proposal for generation of shape invariant potentials using supersymmetric quantum mechanics is introduced. For this purpose the potential term in the Schrödinger equation is expressed in terms of the super potential.The obtained equation transformed into well known ordinary second order differential equation. Using standard technique, the Nikiforov-Uvarov (NU) method the superpotential in the Schrödinger equation is expressed in terms of the parameters appeared in the NU-approach concluding to a nonlinear differential equation. By solving the obtained equation and using relation between superpotential and potential the shape invariant potentials are obtained. The proposed method is general and straightforward for introducing of the shape invariant potentials.
