Magnetic field dependence of the effective penetration depth ($$lambda$$) determined by $$mu$$SR is reported for $$1H$$-Ca(Al$$_{0.5}$$Si$$_{0.5}$$)$$_2$$, a structurally new phase of Ca(Al$$_{0.5}$$Si$$_{0.5}$$)$$_2$$. The new phase has an AlB$$_2$$-type crystal structure with $$P$$3 symmetry which, in contrast to earlier reports, does not exhibit superlattice structure along the $$c$$-axis. The bulk susceptibility measurement indicates that the upper critical field is much lower than that in superstructured ones for both $$c$$- and $$a$$-axis directions. A weak anisotropy in the superconducting order parameter is suggested from the increase of $$lambda$$ with increasing external field.
