  propagation space
One of the most important results of our paper is that the propagation space equations are no longer partial differential equations but they are in terms of pseudo-differential operators.
      
We have first derived the propagation space equations in the long wave limit and also given a general procedure to derive these equations for arbitrary wave length, when the flow is irrotational.
      
Finally, typical nonlocality is introduced for nonlinear Rayleigh surface waves, and general comments on more general two-dimensional (in propagation space) nonlinear strain waves on structures are evoked by way of conclusion.
      
We identify the key parameters that characterize the dimensions of the signal spaces and the degrees of freedom in the propagation space.
      
The overall MIMO channel is determined by the interaction between the signal spaces and the propagation space.

The spatial propagation properties of output annular laser beam from an unstable resonator are studied based on Fresnel diffraction integral. According to the position of extreme value point of laser intensity on the axis, the formula used to divide the propagation space of output beam from unstable resonator into near field, middle field and far field is derived. The numerical calculation shows the variation process of output laser beam of unstable resonator from annular pattern on near field, with gradual...

The spatial propagation properties of output annular laser beam from an unstable resonator are studied based on Fresnel diffraction integral. According to the position of extreme value point of laser intensity on the axis, the formula used to divide the propagation space of output beam from unstable resonator into near field, middle field and far field is derived. The numerical calculation shows the variation process of output laser beam of unstable resonator from annular pattern on near field, with gradual transition of laser energy in the annular region to the beam's center, to Airy disk pattern on far field. The experimental results obtained in TEA pulsed CO2 laser with unstable resonator are in good agreement with theoretical results.

The resonant frequencies of the NBS TEM cell have been calculated by the Finite-Difference Time-Domain (FD-TD) and irregularly graded Ttansmis-sion-Line Matrix(TLM) methods. In the calculating process by the FD-TD method a novel processing method for the magnetic wall boundary conditions is developed with which it is possible to treat only one eighth of the whole cell domain to calculate the resonant frequencies. As a result, additional useful resonant frequency data are listed. In the TLM meth ,d, the propagation...

The resonant frequencies of the NBS TEM cell have been calculated by the Finite-Difference Time-Domain (FD-TD) and irregularly graded Ttansmis-sion-Line Matrix(TLM) methods. In the calculating process by the FD-TD method a novel processing method for the magnetic wall boundary conditions is developed with which it is possible to treat only one eighth of the whole cell domain to calculate the resonant frequencies. As a result, additional useful resonant frequency data are listed. In the TLM meth ,d, the propagation space of the TEM cell is irregularly graded according to the nature of it. The results show that the coarseness error is reduced. Finally, a comparison between the results of two methods is given, which shows good agreement with each other.

本文分别用FD-TD(时域有限差分)法和不均匀划分TLM(传输线矩阵)法计算标准TEM小室的谐振频率。在FD-TD法的计算中,提出一种新的磁边界条件的处理方法,节省了计算量,给出了大量未曾发表过的标准TEM小室内谐振频率的计量结果。在不均匀划分TLM方法的计算中,按小室的自然结构不均匀的划分小室内的传播空间,也达到了节省计算量的目的。最后,对这两种方法和计算结果进行了比较。给出了若干结论。

According to a study on the explicit difference method of 3CDD wave equation and an introduction of a weighting factor used in linearized processing of stable constraint whose module is less than 1,the authors proposed a designing method about 1D explicit short operator based on quadratic programming. Different from conventional methods, the maximum module in propagation space is also limited in order to gilarantee the stability of wave field extrapolation in deeper area. At the same time, a (3D) wave field extrapolation method in depth given based on 1D explicit operator and McClellan transform can lower computing amount and increase calcuation velocity, it can also adapt to transverse inhomogeneous media.

通过对三维波动方程的显式差分法的研究,并对模小于1.0的稳定性约束作线性化处理时引入加权因子,提出了一个基于二次规划方法的一维显式短算子设计方法。与以往的显式算子设计方法的不同之处,在于对传播区内算子的模也引入了最大值限制,这样可更严格地保证深层波场延拓的稳定性。同时,给出了基于一维显式算子及McClellan变换的三维波场深度延拓方法,大大减少了计算量,提高了计算速度,并能更好地处理介质横向非均匀性。
