  2. Overview • Novel Visualization Approach for Field Quantities Projects Quantities on the Surface of a Sphere • Uses Color to Indicate the Magnitude of a Field Component • Allows Ready Visualization of Angular Distribution of Field Quantities • Allows Visualization of Field Quantities as they change with distance from the Radiation Source by Plotting Multiple Spheres or as movies

  3. Thin Dipole Example North Pole South Pole Equator Z Y Normalized Far – Field Pattern E (  , ) X

  4. Thin Dipole Example E – Field Patterns Normalized to R = 0.1  E ( r ,  , ) R = 0.2  E ( r ,  , ) R = 0.1 

  5. Thin Dipole Example E – Field Patterns Normalized to R = 0.1  Er ( r ,  , ) R = 0.1  Er ( r ,  , ) R = 0.2 

  6. Thin Dipole Example H – Field Patterns Normalized to R = 0.1  H ( r ,  , ) R = 0.1  H ( r ,  , ) R = 0.2 

  7. Thin Dipole Example Poynting Vector Field Patterns Normalized to Radial Component S ( r ,  , ) R = 0.1  Sr ( r ,  , ) R = 0.1 

  8. Thin Dipole Example Poynting Vector Field Patterns Normalized to Radial Component S ( r ,  , ) R = 0.2  Sr ( r ,  , ) R = 0.2 

  9. Summary • Provides a Novel Mechanism for Visualizing Field Quantities • Many Extensions of the Concept Possible
