This paper presents an new modeling method that RF MEMS device is divided into some typical structures, which can be considered as different transmission lines and be modeled respectively to get equivalent circuit model of the device by cascading. Applying the modeling method to DMTL, the equivalent circuit model and the relationship between model parameters and physical size are obtained after MEMS...
Dynamic echo is the basis to analyze and discriminate the features of precession targets, but it is difficult to acquire the outfield data with small cost. In this paper, precession model of a general target is built, and the attitude formulas of elevation and azimuth are derived respectively. On the basis of the static electromagnetic scattering data, a scheme is proposed to simulate the dynamic...
In this paper a synthetic aperture (SA)-based ultra wideband (UWB) imaging system with broadband adaptive processing is proposed for general medical applications (e.g. breast cancer, water accumulation in bladder, etc.). For the signal processing, a broadband version of minimum variance distortionless response (MVDR) is implemented. To demonstrate the efficiency of the method, it is applied to an...
A necessary step to building effective writing skill training system requires developing good methods for modeling human skill adequately. A number of groups have represented character information in various languages for writing skill based on trajectory information. These methods are often data intensive, tedious to implement and do not encode force information. To overcome these restrictions a...
First the surface-potential-based compact MOS model, PSP, is introduced. After a discussion of the general advantages of this model, it is benchmarked against measurements from the 45 nm technology node. Finally, we zoom in on the modeling in PSP of two effects that are of special importance for RF applications: distortion and noise.
