A planar capacitor analysis by EM simulator
A planar capacitor--a parallel-plate capacitor is seen in a textbook of electromagnetics. But I have scarcely seen modified ones other than the basic type. For example, electrodes of a capacitor are horizontally shifted or have different size or shape from the other one. I analyzed the variation of capacitance of a planar capacitor.
'Mr. Smith'--An Impedance Calculator on the Smith Chart
'Mr. Smith' is a calculator of impedance on the Smith Chart. It displays traces of impedance objects on the Smith Chart as you draw traces on a sheet of paper-form Smith Chart by a pencil. It eliminates paper-form Smith Chart in designing a reactance circuit.
