• Sep 29, 2025 fingerprint and iris recognition using matlab code to a normalized rectangular block (rubber sheet model). This process compensates for size variations and pupil dilation. Feature encoding often employs: Gabor filters Wavelet transforms Log-Gabor filters These extract texture features, resulting in a binary iris code, w By Akeem Heidenreich
• Oct 8, 2025 fiber laser simulation matlab n inversion levels in the dopant ions, governed by rate equations, is fundamental. These equations describe how the populations change with pump and signal intensities. 2. Light Propagation and Nonlinear Effects The evolution of the optical field within the fiber is described by the nonl By Ada Dietrich
• Apr 13, 2026 fiber bragg grating simulation matlab refractive index between the grating regions and the surrounding fiber. Length of the Grating (L): How long the grating extends along the fiber. How FBGs Work When broadband light is transmitted through the fiber, the FBG reflects By Ally Mitchell-Schaden
• Jul 28, 2025 fdtd code matlab dispersion diagram gram visualizes the relationship between the frequency (\( \omega \)) and the wavevector (\( k \)) of waves propagating through a medium. It reveals how the phase velocity and group velocity vary with frequency, providing insights into phenomena such By Aglae Kunze
