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.

This Design Idea applies a noveltopology to an oscillator. It usesa series-connected LC (inductive-capacitive)tank circuit to give the circuita higher tuning range than circuitsthat use a parallel-LC ...

In So you think you understand transmission lines, I offered a seeming paradox about a property of transmission lines. If you look at the input impedance of a uniform transmission line, open at the ...

We wish that all the beautiful animations that are available today to understand math and electronics had been around when we were in school. Nonetheless, they are there for today’s students and ...
