✦ Synopsis

radial stub has been presented. Although the curvilinear FDTD gives quite accurate results, it leads to larger computer requirements than a simpler staircasing approximation. Indeed, depending on the geometry of the metallizations, the mesh constraints can be a serious limitation. The method is more suitable for actual 3-D structures with curved dielectric boundaries. As a conclusion, it has been successfully applied to predict the performances of cylindrical microstrip antennas and arrays with small curvature radii.

In any case, the FDTD method in curvilinear coordinates appears as an efficient and versatile tool for a large range of applications. Not only can structures with curved metallizations be simulated, but ones with curved dielectrics can be as well.

A new time-domain technique for determining the radiation Q of an antenna is presented. The time integral of power returning to the antenna from the standing energy field upon source turn off is determined numerically, and is used as a measure of the peak standing energy for Q determination.

This paper deals with the numerical modelling of arbitrarily shaped curved antennas by marching on in time (MoT) technique. This time domain version of the method of moments (MoM) is particularly suitable for transient analysis and, in this respect, is more e$cient than the frequency domain approach

If the antenna factor is defined as the ratio of incident electric field strength to the output voltage with zero reflection at the load, relative measurement of the antenna factor can be carried out using a reference antenna with a known antenna factor. In this study, an antenna factor of a log dip

The dry-cast membrane-formation process is a principal technique by which asymmetric porous membranes as well as dense films can be obtained. Much insight into the fundamental nature of this process can be obtained via real-time measurements of mass and thickness changes. The former requires an equa

A fundamental problem in the assessment of dementia is the brief, but adequate measurement of intellectual impairment. We evaluated 82 demented patients of heterogeneous etiology with 21 neuropsychological tests. Factor analysis identified five deficit domains among the tests: verbal ability, visuos
