Online solvers, technical remarks

---

The solvers are encoded as (unsigned) Java-applets. This implies

The programs are meant as a kind of pocket calculator for rough and quick assessment of problems involving slab waveguides, and for purposes of demonstration. The limited functionality is hardly sufficient for more extensive design tasks, where one should resort to other computational means. Analogous programs (e.g. the Metric tools) are available from this site, without a graphical user interface, but applicable to a substantially larger variety of problems.
