%0 Journal Article %T Lie Symmetries and Exact Solutions of 2D Proper-Time MaxwellˇŻs Equations %A Joshua Owolabi Adeleke %J Open Access Library Journal %V 12 %N 10 %P 1-9 %@ 2333-9721 %D 2025 %I Open Access Library %R 10.4236/oalib.1114285 %X We present a Lie symmetry classification of 2D proper-time Maxwell’s equations, deriving an 8-dimensional Lie algebra and constructing rotationally invariant Bessel function solutions and self-similar solutions with Hadamard regularization. A central-difference/Verlet scheme is stable under the standard Courant condition for numerical solutions. The results model transverse plasma waves in relativistic jets and particle beams in plasma wakefield accelerators [1], preserving causality via u μ u μ = c 2 , where u μ is the 4-velocity, using the Minkowski metric η μν =diag( 1,1,1 ) . Here, b= c 2 u x 2 u y 2 is the propagation speed, γ=b/c is the Lorentz factor, and ζ=r/τ is the similarity variable.Subject AreasElectric Engineering, Theoretical Physics %K Electrical Engineering %K Theoretical Physics %K Lie Symmetry Analysis %K Proper-Time Formulation %K MaxwellˇŻs Equations %K Conservation Laws %K Exact Solutions %K 2D Wave Equation %U http://www.oalib.com/paper/6874884
