It bugs me that after all this time talking about this, we still don't have answers to several key questions about the technology they are claiming to have used for the detection of that plane. Such as was it done with satellite images or were planes involved, analog or digital images, from which sat, how old were the pictures, ... The thing is that many possible combinations of answers would already prove it can't work. They can't search the entire ocean with planes within any reasonable time, they can't get any "hidden data" from digital pictures, they likely couldn't have access to recent analog sat photos etc. The odd thing isn't that they haven't given such answers, but that apparently nobody has asked them. Without those answers it's also pretty much impossible to know if we are even arguing about the impossibility of right technologies.
It doesn't bug me at all. They are not going to provide any details. I suppose that I could contact them pretending to be someone interested in their technique, but that is a total waste of my time.
The answers for the GR use of multispectral imagery to see through any material are provided by the equation: d(λ, χ) = λ/4πχ. All you need to do is look for tables of the complex index of refraction for various materials, the equation will provide the depth of penetration as a function of wavelength. I have provided an example for water for people to play with (easily done in Excel).
Here is a link with a number of materials (some are Fortran subroutines, make me feel nostalgic!):
This is the underlying equation of EM wave propogation:
Wave Equation with Dispersion:
E = E0 exp(i(kz – ωt)) exp(-ωχz/c) (Martin, 2004)
E Electric field in a lossy medium (V/m)
E0 Reference field (V/m)
z Distance (m)
t Time (s)
ω Frequency (Hz)
c Speed of light (m/s)
χ imaginary part of index of refraction
k vector wavenumber (1/m) (note: k = ωn/c)
Complex Index of Refraction:
η = n + iχ
exp(i(zωn/c – ωt)) is the wave propagation (e raised to an imaginary number produces a "sine" wave)
exp(-ωχz/c) is an exponential decay (e raised to a negative number produces an exponential decay)
