1. Coupling and reciprocity

A reminder of oscillators

Consider the series combination of three passive elements (R resistor, L inductor and C capacitor). The relationship between the voltage u (t ) across this circuit and the current i (t ) through it can be written as a second-order differential equation with constant coefficients: $\frac{d u}{d t} = L \frac{d^{2} i}{d t^{2}} + R \frac{d i}{d t} + \frac{i}{C}$

If the imposed voltage...
