Pretty cool, could become great utility – jEMLab Review

Some nice demos, could become a great RF utility if you could do things in return loss/ VSWR instead of reflect. coefficient; either have all, or make units selectable via preferences. Other useful labs would be: views of VSWR in dBs as well as voltage; maybe signal ripple (dB p-p) vs. Coherent Interferer signal level (level defined via slider); antenna gain & beamwidth vs. Dish size, frequency.
