# Application Example: Microstrip with a Lumped RLC element

Calculate the power reflected by a lumped RLC element in a transmission line at RF frequencies using FDTD Solutions and MODE Solutions (FDE).

In this example we study a microstrip transmission line with a lumped RLC element in the middle. We calculate the reflected power for different settings of the RLC element in a 3D FDTD simulation and we compare with analytical results. We also show how the results can be visualized in a Smith chart.
