Optical systems combining balanced loss and gain provide a unique platform to implement classical analogues of quantum systems described by non-Hermitian parity–time (PT)-symmetric Hamiltonians. Such ...

Surprising facts, like “old fangled” 3-leg linear regulators (LM317, LM337, LM350, et al.) can be used in shunt regulator topologies can sometimes inspire “new fangled” circuit designs. Figure 1 shows ...

Figure 1: Comparison between conventional and PT-symmetry-based wireless power transfer schemes as the source–receiver resonant coupling rate κ varies as a function of transfer distance d. Figure 3: ...

This blog comes from my discussions with Steve Savoie, a manufacturing and tooling engineer who spoke at last year’s International Boatbuilders Exhibition (IBEX). Steve has a background in both ...
