  We explore the multiwavelength radiation properties of the light curves and
energy spectra in the dissipative magnetospheres of pulsars. The dissipative
magnetospheres are simulated by the pseudo-spectral method with the combined
force-free and Aristotelian electrodynamics, which can produce self-consistent
accelerating electric fields mainly distributed in the equatorial current sheet
outside the light cylinder. The multiwavelength light curves and spectra are
computed by using the multiple emission mechanisms of both the primary
particles accelerated by the accelerating electric fields in the equatorial
current sheet and the secondary pairs with an assumed distribution spectrum. We
then compare the predicted multiwavelength light curves and spectra with the
observed data from the Crab, Vela, and Geminga pulsars. Our modeling results
can systematically well reproduce the observed trends of the multiwavelength
light curves and the spectra for these three pulsars.
