This is the net power flow accepted by the structure from all ports. The sum of all powers per port is given in the root folder as Power Accepted. For each port it equals the sum of all net power flows per mode. In the subfolder Power Accepted per Port you can find information about power that entered or left the calculation domain via the ports. Please note that these curves are only shown for waveguide ports that monitor only. In the subfolder Power Accepted per Mode you can find the net power flow for each mode of a waveguide. Consequently the combined average stimulated power equals 2.5 W for every frequency. Using simultaneous excitation or the combine calculation results feature the mode amplitude can be reset e.g. For a single excitation the power stimulated power is 0.5 W for every frequency.

The default values for the excitation amplitudes are chosen according to the normalization overview.Įxample: Consider the following dual patch antenna with two ports, where two ports have been excited separately by the time domain solver with amplitude 1 sqrt(W) each. If there are N excited modes, the port is stimulated with the power Please note that for a waveguide port the amplitudes might be individually set for every mode. The sum of all stimulated powers per port is shown as "Power Stimulated".

This curve shows the overall power the structure is stimulated with by excitation sources.įor every port with active excitation, the stimulated power is calculated from the power that is delivered by the signal generator to the port. The Power that is stimulated at one or more ports will be divided into the power which is accepted by the structure and the power which is again leaving the structure via the ports ( outgoing power).įurthermore the accepted power is converted either into losses (losses in dielectrics, metals or lumped elements) and/or is radiated for example in case of antenna applications.
In the Power folder all loss and power curves are contained for performed excitations.Īdditional subfolders show the total power values separated e.g. In the picture below you see an exemplary tree structure of the power folder as well as a schematic diagram of the power balance representation. a port number, a simultaneous excitation label or 'pw' in case of a plane wave excitation. Correspondingly, the text in square brackets indicate the name of the excitations, e.g. This folder is located beneath the 1D Result folder and contains subfolders representing the performed simulation runs with different excitations.
ContentsĪll power spectra curves available in CST Microwave Studio are averaged over one period in time at every frequency and collected inside the Power folder. Below you will find a detailed description and some example curves for the different power curves.

Depending on the type of application, the stimulated power, that is fed into the structure, might divide into power dissipated into lossy materials and lumped elements, power that is radiated into free space and finally power leaving again the structure through ports. In CST Microwave Studio a special power view is available, which helps to better understand the behavior of a device by analyzing its overall power balance.
