  4. VEMSA3D - The Starting Window

  5. VEMSA3D - Menus and Dialog Boxes

  6. VEMSA3D - Simulation Results : 1/2 2D and 3D E - U Radiation Patterns Industrial StandardThe Half-wave Dipole : 9 modes

  7. VEMSA3D - Simulation Results : 2/2 Commercial Antenna HUF TV : 723 modes

  8. VEMSA3D - Comparison - Simulation Results with Measurements : 1/4 Experimental Antenna Array of 2 dipoles : 73 modes

  9. VEMSA3D - Comparison - Simulation Results with Measurements : 2/4 Amateur Antenna"Hentenna" : 109 modes

  10. VEMSA3D - Comparison - Simulation Results with Measurements : 3/4 Experimental Antenna Monopole over a counterpoise : 167 modes

  11. VEMSA3D - Comparison - Simulation Results with Measurements : 4/4 Experimental AntennaA Monopole over a Counterpoise over a Wired-Disk : 2,594 modes

  12. VEMSA3D - Comparison with Freeware 4NEC2X : 1/2 Antenna on Airplane VEMSA3D : 391 modes

  13. VEMSA3D - Comparison with Freeware 4NEC2X : 2/2 Horn with Bow-Tie feeder, by Pittra and Raida, 2010 1,370 modesfrom 1,206 segments =< 1,500 max segments of 4NEC2X

  15. VEMSA3D - Unique Characteristics : 1/3 VEMSA3D is developed in C++ as /F/L/O/S/S/ Free Libre Open Source Software

  16. VEMSA3D - Unique Characteristics : 2/3 Horn with Bow-Tie feeder, by Pitra and Raida, 2010 3,266 points - 4,362 segments5,458 modes

  17. VEMSA3D - Unique Characteristics : 3/3

  18. VEMSA3D - Main Conclusions VEMSA3D - is only limited by computing resourves and time, - is Free Libre Open Source Software Code for everybody, - is expandable by anyone, -surpasses any restriction imposed by any authority on modeling points, segments or modes of any other Visual Electromagnetics Antenna Simulator, either freeware or commercialware.
