This means that the total resistance is the radiation resistance of the surface encapsulating particles. The radiation was 35 db in a shape close to that of a sphere. (when the resistance of the aluminum dipole went to zero the radiation went to a perfect sphere) Efficiency was stated at 100% efficient pointing to 100% accountability for all forces involved and where losses were at a minimum. Regards Art Extra information When resonant at 50 ohms resistive the donut shape was evident and provided by two vortices. As the resonant value dropped so did the depth of the two vortices At 5 ohms resistive the vortice depth really started to reduce in depth.In other words as the vortice reduced so did the skin depth and Wow! I'd really like to see this vortex, sorry these vortices, that you have produced. Is the rotation right or left handed? This is REALLY COOL! Please post the file and which optimizer software that you are using. Thanks! tom K0TAR |
