A numerical model for investigating the localization of surface exciton polaritons in the presence of random roughness and spatialdispersion was established.
在存在着随机粗糙和空间色散时，利用了一个数字模型研究表面激子极化激元的定域化。

A double focusing, non spatialdispersion magnet design has been suggested to substitute the achromatic principle for improving the beam characteristics on target of the medical accelerator.
Then the article discusses forward modeling based on acoustic wave higher difference, then analyzes numerical dispersion including time and spatialdispersion and presents its stability conditions.
