An interactive introduction to the chart at the heart of RF engineering.
At Arena Physica, our mission is to build electromagnetic superintelligence. We recently adopted a new logo inspired by the Smith chart, which harkens back to the origins of radio frequency engineering. We wanted to use this opportunity to give a brief technical introduction to what a Smith chart is and why it's so important to us. Before we can get to the Smith chart, we first need to understand impedance. Electrical "resistance" is something that resists the flow of direct current in a circuit (and corresponds to the RR in Ohm's law: V=IRV = IR). Electrical "impedance" generalizes the…
