| Abstract: | The dispersion relation of electromagnetic waves in an unmagnetized,collisionless and isotropic relativistic plasma with a modified kappa distribution was investigated.The analytic formulas of dispersion relations under the long-wavelength and the short-wavelength approximations were derived.Using the numerical calculation method,the full dispersion curve was obtained.The results indicated that the analytical dispersion curves in the long-wavelength and short-wavelength regions coincided with the numerical ... |
