The solutions of ${\color {white}\boxdot \ \psi =(\nabla _{r}\nabla _{r}+\langle {\vec {\nabla }},{\vec {\nabla }}\rangle )\psi =0}$ We focus on warp shock fronts of the form ${\color {white}{\vec {\psi }}=f_{r}(c\tau -{\vec {r}})\,{\vec {i}}}$ The real scalar ${\color {white}c}$ equals the speed at which the shock front travels The vector ${\color {white}{\vec {r}}}$ is the distance from the trigger location to the shock front Vector ${\color {white}{\vec {i}}}$ represents the amplitude of the front, which directs perpendicular to ${\color {white}{\vec {r}}}$ The function ${\color {white}f_{r}(q)}$ is a real function that describes the shape of the front in the direction of ${\color {white}{\vec {r}}}$ In the string the direction of vector ${\color {white}{\vec {i}}}$ may rotate as a function of the sequence number of the warp. This gives the string a circular polarization Circular polarization of warp string. The arrows represent the amplitudes of the warps that constitute the string. The red line is a help line. No wave is involved!
