  We solve the Weyl electron scattered by a spherical step potential barrier.
Tuning the incident energy and the potential radius, one can enter both
quasiclassical and quantum regimes. Transport features related to far-field
currents and integrated cross sections are studied to reveal the preferred
forward scattering. In the quasiclassical regime, a strong focusing effect
along the incident spherical axis is found in addition to optical caustic
patterns. In the quantum regime, at energies of successive angular momentum
resonances, a polar aggregation of electron density is found inside the
potential. The findings will be useful in transport studies and electronic lens
applications in Weyl systems.
