I am far from an expert on electromagnetic issues but someone who is explained it to me in an example most will understand
If I have a flashlight with 2,000 lumens that is the most light it is capable of producing. If that flashlight has a 'Focus Lense' I can use it as a 'Flood Light' to spread its 2,000 lumens over a wide area or I can use it as a 'Spot Light' to condense those 2,000 lumens into a narrow beam.
Reducing the ActiPatch antenna diameter size focuses its energy on a smaller area similar to the 'Spot Light' setting on a flashlight.
As for the rectangular shaped antenna on the new ActiPatch Surgical Incision device it may be covering a smaller square cm area but the big plus I see is placing the antenna wire very close on both sides of the incision. If you have ever had a large bruise and used an ActiPatch on it the area right under the antenna wire heals the quickest, returning to your normal skin color while the rest of the bruise is still discolored. That is because it receives the strongest signal.
For the nerds I got an opinion from AI but ihub could not handle the equations;
Question - A wearable PEMF device has a 12cm antenna, sending a 27.12 MHz signal, pulse frequency of 1000 Hz and a pulse width of 100 microseconds, and peak spatial power density of 73 microWatts/cm2, does the power within the treatment area increase if the antenna is reduced in size to 6cm?
Answer - To determine if the power within the treatment area increases when the antenna size is reduced from 12cm to 6cm, we need to understand how changing the antenna size affects the power density.
Given:
Frequency (f): 27.12 MHz
Pulse frequency: 1000 Hz
Pulse width: 100 microseconds
Peak spatial power density with the 12cm antenna: 73 microWatts/cm²
To analyze the effect of antenna size on power density:
Calculate the power radiated by the 12cm antenna using the given parameters.
Calculate the power radiated by the 6cm antenna using the same parameters.
Compare the power densities of both antennas.
The peak spatial power density (S) can be calculated using the formula:
Where:
?
P is the power radiated by the antenna.
?
A is the area over which the power is distributed.
For both antennas, the pulse width and pulse frequency are the same. Therefore, the power radiated by the antennas is the same.
The only difference between the two antennas is the area over which the power is distributed.
For the 12cm antenna:
113.1 cm2
For the 6cm antenna:
28.3 cm2
P is constant for both antennas, the power density is inversely proportional to the area. Therefore, the power density increases as the area decreases.
So, when the antenna size is reduced from 12cm to 6cm, the power density within the treatment area increases.
