Abstract :
The main results of the modeling of an open ended coaxial probe on a thin layer are shown. If measurements on a multilayered structure are performed, it is important to know in how far the lower layers are detected by the probe. A numerical method is used based on a full-wave solution for an open ended coaxial probe. Knowing the thickness of the upper layer gives immediately an idea of the dimensions of the probe if one only wants to measure the properties of this upper layer
