The Green's func- tions associated with planar excitations are briefly recalled, and the method to compute them is generalized to vertical current sources, yielding new components of the Green's function necessary for the anal- ysis of vertical metallizations embedded in waveguides or cavities. %K Teoría de la Señal y las Comunicaciones %K Waveguide Green's functions %K Integral equation technique %K Shielded microwave circuits %K Vertical interconnects %K Via-holes %~ GOEDOC, SUB GOETTINGEN
