Engineers have succeeded in fabricating topological LC circuits arranged in a honeycomb pattern where electromagnetic (EM) waves can propagate without backscattering even when pathways turn sharply.

I love technical puzzles and challenges. In working on my next signal-integrity textbook, I came across this commonly occurring situation that had me stumped for a few minutes. Maybe it will entertain ...

If you catch a grizzled old radio amateur propping up the bar in the small hours, you will probably receive the gravelly-voiced Wisdom of the Ancients on impedance matching, antenna tuners, and LC ...
