Abstract: The superfluid $^3$He B phase, one of the oldest unconventional fermioniccondensates experimentally realized, is recently predicted to support Majoranafermion surface states. Majorana fermion, which is characterized by theequivalence of particle and antiparticle, has a linear dispersion relationreferred to as the Majorana cone. We measured the transverse acoustic impedance$Z$ of the superfluid$^3$He B phase changing its boundary condition and found agrowth of peak in $Z$ on a higher specularity wall. Our theoretical analysisindicates that the variation of $Z$ is induced by the formation of thecone-like dispersion relation and thus confirms the important feature of theMajorana fermion in the specular limit.
