The First All New Resonant Line in Thirty Years

NOTE: Submitted to CARTS 2014 Introduction The resonant line technique began at MIT Electrical Insulation Laboratories during WWII. The method satisfies a basic need to measure low losses in large reactive loads. The technique is to cancel the reactance of the load with a known (calculable) reactance, leaving the losses […]

CAD Project for Single Layer Capacitors

What is a capacitor? [1] ca·pac·i·tor /kəˈpasitər/   Noun A device used to store an electric charge, consisting of one or more pairs of conductors separated by an insulator.   But… “one or more pairs of conductors separated by an insulator” can also be a transmission line. It turns out that […]
