Abstract:Analysis of the millimeter wave propagation in a rectangular dielectric waveguide using the FDTD method is presented. In comparison with other methods,the FDTD method is not restricted in the cases of higher or lower permittivity, and good results can be reached even at high permittivity. By using the FDTD method,the propagation constant of each mode as well as its field distribution can be obtained.

Abstract:A new kind of correlation detection technique was presented. On the basis of frequency modulation,the time-division detection was used and the double correlations of frequency and time were realized. By the technique, when applied in the plane detecting system with parallel infrared rays,the DC and adjacent radiation interference can be removed completely, thus making the reliability and accuracy of the IR plane detecting system improved greatly.

Abstract:The infrared radiance statistics of natural terrain in a random wind field was analyzed based on the heat balance equation,in which the effects of latent and sensible hea texchanges and atmospheric thermal radiation are under consideration. The results show that the statistics distribution,average value,variance,skewness and kurtosis of radiative temperature of bare terrain vary not only with the average wind speed,but also with the fluctuation of wind. As a result of the latent heat exchange, the average temperature of natural terrain is obviously lower than that of dry bare ground,where there is no latent heat exchange.

Abstract:Two-dimensional image formation in OCT system was analyzed based on the weak object approximation. It was proved that the OCT system behaves as a linear shift inyariance system. The derived 2-D CTF shows that the system performs as a low-pass filter. Smaller distance between the fiber and the lens will not spoil the performance seriously. Decreasing the focus and enlarging the pupil will broaden the system bandwidth, and improve the imaging performance.

As an example,the transmission characteristics of the partially filled rectangular waveguides were calculated numerically,which can show good agreement between the results with the present theory and with the others.

Abstract:The nonlinear effects of stopband shift downward and widening induced by the magnetostatic surface wave power in ferromagnetic slabs with bouble corrugated surfaces were investigated. The spatial phase difference between the two surfaces of the slab has significant influence on the width of stopband and weakens the nonlinear effects of the wave power. Under certain conditions it makes the stopband of the system disappear.

Abstract:On the basis of theoretical study, experiments on passive microwave remote sensing used in the earthquake prediction were carried out. Loading experiments on rock samples of different properties and structures were made. It was obtained that the microwave radiation energy of rock samples changes obviously along with the change of stress state. The amplitudes of the change are different in different wave bands. The amount of variation with stress of different polarization is different. The variation of microwave radiation energy can be measured by microwave remote sensor on satellite. The obviously anomalous information of microwave radiation before rock failure was also discovered by experiments.

The influence of different laser frequencies on the DNA system chaos was discussed and the genetic variation phenomenon caused by laser in a large frequency range was explained.
