Wave active filters represent another approach, proposed by H. Wupper and K. Meerkötter [142, 143], to simulate LC filters where the components are described using waves. That is, instead of using the port current and voltage to describe a port, incident and reflected waves are used. The incident and reflected waves are a linear combination of current and voltage. Hence, we have performed a linear coordinate transformation from the variables current and voltage to incident and reflected waves.

Notes
- 1.
Power waves, which normally are used in the literature for microwave filters, are defined as \(x_1=V_1/\sqrt{R_1}+\sqrt{R_1}I_1\) and \(y_1=V_1/\sqrt{R_1}-\sqrt{R_1}I_1\) [70]. The name comes from the fact that x 2 and y 2 have the dimension power.
