We had previously reported on the optical non-Hermite skin effect in uniform anisotropic media with MT symmetry, where propagating skin modes that neither attenuate nor amplify are obtained. In this study, we report simulations of propagating skin modes in FP cavities with this media. In this system, skin modes with opposite rotation at the left-right and top-bottom boundaries were obtained simultaneously, and it was confirmed that the optical OAM can be generated by breaking the aspect ratio of the system shape from square.
