OSCAR achieves high-ratio lossy compression of wave fields by exploiting on-shell Fourier confinement in weakly scattering media, preserving second-order statistics for direct computation in compressed space.
For a uniform grid with spacing ∆x, the continu- ous relationk 2 =P i k′2 i becomes [17] ω c 2 ¯ε∆x2 = 4 dX i=1 sin2 k′ i∆x 2 ,(8) which reduces to the continuum limit as ∆x→0
