1. Manual Port Synthesis/Characteristic Mode Port Synthesis: FEKO Plate Example
FEKO Project plate_32bit
Frequency: 600MHz – 800MHz with 50MHz spacing
Input file “MANUAL_SYNTHESIS_INPUT.txt” or “CMPS_INPUT.txt”
project.mat (without the extension)
Use existing Y-matrix
Number of ports
Port global index numbers (from CharM GUI)
Port voltages (manual excitation) or CM coefficients (CM port synthesis)
Need to run CharM CM solver BEFORE MS/CMPS
Port 3
Port 2
Port 4
Port 1

2. Manual Synthesis (MS)/CMPS: Input/Output
Project directory before running Manual Port Synthesis.exe
CM computation parameters (e.g. matrix size, number of frequencies, etc) from the CharM CM solver
MS/CMPS executable
MS/CMPS input file
project.mat
Project directory after running Manual Port Synthesis.exe
MS/CMPS output files:
CM expansion, input impedance, Q, etc. (MS_computation_parameters_project.txt)
Surface current due to manual voltage excitation (MS_full_currents_project.txt)
Manual port voltages (MS_voltages_project.txt)
Y-matrix binary file (project.ymat)
Need AEM to convert MS_full_currents_project.txt into *.str and *.ffe files

3. MS/CMPS: Computation Parameters
MS/CMPS executables computes the CM expansion, power radiated, Q-factor, and active input impedances
Plots of these quantities can be put in CharM
Power radiated by the surface current
Characteristic Mode coefficients of the surface current
Q-factor of surface current
