Compared with bistatic RCS, the monostatic RCS calculation is more difficult for the needs of surface current on scatterer induced by the incident wave of every single angle, so the calculation burthen is very large. Based on the character of "coefficients matrix of FDFD equations is invariable whether the angle of incident wave was changed", this paper proposes a fast algorithm for monostatic...

Based on the mode-matching technique and simulation software CST, this paper analyzes and simulates the input cavity of gyroklystron amplifier, and gets the structure model of TE01 mode W-band gyroklystron input cavity. Then it contrasts the influence of the size of coupling slots to the coupling frequency and Q-value.
The web search data, which recorded hundreds of millions searchers' concerns and interests, reflected the trends of their behavior and provided essential data basis for the prediction study of the visitors per-day amount of Shanghai World Expo2010. This paper firstly analyzes the correlation between web search data and the visitors' amount per-day of Shanghai World Expo2010, and then builds a conceptual...
