The topology of a cross section for a wave vector to the power 2. A square of effective refractive index for waves entering a double anisotropic optical medium when these are polarized in a plane of incidence (1) and normally to it (2). The crystalline medium parameters are: εxx = εyy = εzz = 4; μxx = μyy = μzz = 2; εik = 1; μik = 1
