The ability to keep connected with the Internet while on the move is highly desirable in an increasingly mobile environment. In this proposal, we present a mean for ubiquitous network access for consumers in both wired and wireless environments. We introduce the concept of multiple-interface/multiple-connection to support high-speed handoff and seamless roaming between different networks (wired and wireless). This is implemented by improving current mobile IP concept, extending existing IP (specifically CMIP and ARP) functions and enhancing current PC device drivers and software. The mobility that is supported by this proposal is based on layer 3 functionality under the OSI protocol layer definition (physical layer and link layer are assumed to be supported already).","PeriodicalId":354225,"journal":{"name":"ICMMT 2000. 2000 2nd International Conference on Microwave and Millimeter Wave Technology Proceedings (Cat.

In this paper, the antenna array is separated into two parts, the feeding sub-system and the radiant sub-system. Simultaneously, the radiant sub-system is equivalent to an n-port network. Two steps are taken. First, a set of voltage equations is presented according to the transmission line theory, where the voltages, currents, and impedance for each port of network are deduced. Second, the relations between total input impedance and that of each port are given. It is indicated that the input impedance of the antenna can be 50 /spl Omega/ by moving the two pistons at the ends and changing diameters of inside and outside conductor of coaxial line.","PeriodicalId":354225,"journal":{"name":"ICMMT 2000. 2000 2nd International Conference on Microwave and Millimeter Wave Technology Proceedings (Cat.

The surface current that produces the correct scattered fields, referred to as the non-resonant mode current, can be obtained by using the singular value decomposition technique or the inverse power method, but it is not the real electric current induced on the object surface. A new method is presented to determine the correct surface current, which is composed of the non-resonant mode current and the normalized resonant mode current multiplied by an unknown complex factor. The unknown complex factor can be obtained by employing the condition that the total field must be zero at specified interior points. A numerical example is given for an infinitely long, perfectly conducting circular cylinder at interior resonance, and the computed surface currents are in good agreement with the analytical ones. The validity and accuracy of the presented method is thus verified.","PeriodicalId":354225,"journal":{"name":"ICMMT 2000. 2000 2nd International Conference on Microwave and Millimeter Wave Technology Proceedings (Cat.

The comparison made for some parameters like the attenuation of the wave, or the signal to propagation noise ratio, shows a very good agreement.
