Absorption and scattering of massless scalar wave from Regular Black Holes

In this work, we numerically investigate the scattering and absorption cross section of massless scalar field from some well-known regular black holes by using partial wave approach. Our computational results indicate that larger parameters, lower associated total maxima. When compared to Schwarzschild hole, is enhanced in hole spacetimes, meanwhile width narrow forward orientation. Moreover, it found null geodesics critical impact parameter geometrical optical value high frequency regime have similar changing behavior.
