Presentation Transcript

  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 Characteristic Mode coefficients of the surface current Power radiated by the surface current Q-factor of surface current
