Dr. Tseung,
Please confirm the model number of your scopes is ADS1102, 100MHZ bandwidth. Then the probes to be used are P6100 100MHz, x1x10 passive probes. Thanks.

Confirmed.

Here is a close up shot of the prototype tested on Jan 8 that produced a COP of -2.2.

It was basically a Joule Thief Circuit with two secondary windings.  The number of turns was selected to completely surround the toroid.  The actual diameter and characteristics of the toroid did not make much difference.  In the experiment on Jan 8, we aimed for maximum sensitivity and any result with COP > 1 was acceptable. 

The COP was calculated from the average of the Output Power divided by the Input Power.  This is the so called true COP.

The actual of -2.2 was obtained.  The negative sign came from the Average Output Power.  There can be different interpretations of the negative sign.  One was - more feedback than supplied power. 

The additional calculation in the ADS00057 and ADS00058 files focused on the positive and negative values separately.  Such calculations highlight the effect of the "standing wave".  In the particular experiment, the result was not a good standing wave and the COP value was low.  This will be improved in the coming experiments.

Experiment on Jan 11a

The air coil toroid was used.  We introduced unecessary wires.  Here is the result.

The result should be compared with shortening the wires to the minimum. in the next post.

Experiment of Jan 11b

The wires were reduced to the minimum length.
