An inverse Compton scattering (ICS) model of pulsar emission

. The shapes of pulse pro(cid:12)les, especially their variations with respect to observing frequencies, are very important to understand emission mechanisms of pulsars. However, no previous attempt has been made to interpret their complicated phenomenology. In this paper, we present theoretical simulations for the integrated pulse pro(cid:12)les and their frequency evolution within the framework of the inverse Compton scattering (ICS) model proposed by Qiao (1988) and Qiao & Lin (1998). Using the phase positions of the pulse components predicted by the \beam-frequency (cid:12)gure" of the ICS model, we present Gaussian (cid:12)ts to the multi-frequency pulse pro(cid:12)les for some pulsars. It is shown that the model can reproduce various types of the frequency evolution behaviors of pulse pro(cid:12)les observed.
