Basic Waveguide Problems

In this section, a set of elementary structures is investigated. These components are essentially embedded in more complex electromagnetic compatibility devices (EMC) devices regarding microwave instrumentations, miniaturized packaging layouts in communication ensembles, power managing tools, and biomedical systems for the estimation of hazardous health effects. Since, their profile may lead to complicated field patterns, it is anticipated that HO FDTD operators will provide the most sufficient results.

Another significant class of problems, whose waveguiding properties require a systematic study, is the PCBs that constitute the basic parts of many contemporary telecommunication or computer devices. A general PCB configuration is shown in Figure 7.16. Most components...
