I was referring to the principles of Radio Wave propagation using an Isotropic antenna (a loss free antenna in free space) as an example.
Antenna Propagation: Basically, when a Radio Frequency is applied to the antenna a changing electro magnetic field is set up around the antenna which changes proportionally to the frequency of the applied RF which in effect is a fast AC (alternating current).
If the frequency is fast enough then the field which is set up initially tries to collapse but due to the short time constant of the wave it never fully collapses before the next cycle comes alongwhich pushes this collapsing field outwards. The direction of the EM wave changes again and another field is set up inside the first two, pushing the first and second waves further outwards.
This continues as long as the Radio Frequency is applied to the antenna. This is how radio waves get fro a transmit antenna to your recievers antenna.
The key factor in all of this is is time. As long as there is not enough time between the RF cycles for the field to fully collapse then Radio wave propagation occurs.
Now here's my analogy. Apply these laws of physics to the physiology of the human body:
The RF is like rapid changes in pressure (on a saw tooth profile or Yo-yo dive) applied to the Antenna (your body in this case). Your body tissues absorb gas at varying rates and also disapate gas at varying rates.
I think we can assume that we all agree that there are tissues in the body which absorb gases faster than they release them for a given symetrical change in pressure (these gases which are left over I will call residual gases for the purpose of explanation).
I'm suggesting that if the next increase in pressure is followed sharply by a decrease in pressure, then an increase again, the rate at which the gas is absorbed into the tissues will increase, (using the radio wave propagation principle as an example), because if the time constant is short between cycles being short and there always being some amount of residual gas left in the tissues before when the next compression cycle comes along.
This type of compression which I have heard described as Adiabatic compression (not Isothermal) occurs in a saw-tooth dive profile and I believe results in an increase of gas absorbed into the tissues compared to a straight line type of ascent and descent.
I hope the Doc can find some conclusive date to substantiate my theory which is based primarily upon pure physics and secondly upon our limited knowledge of barophysiology.
Thanks for your interest
