Abstract
Asymptotic solutions describing linear waves generated by oscillating elliptic source are constructed employing the recently developed “Reference Solution Approach” (RSA). The source is assumed to be in rest. The resulting wave pattern exhibits pronounced anisotropy of the solutions for elongated sources. The classic Kelvin angles of the ship wave patterns determine specific distinguished directions. The analytical results within the RSA are shown to agree remarkably well with the exact linear solutions of the problem.
