We propose a study of pulsars with interpulse (IP) emissions using the Ultra-Wideband Low (UWL) receiver on the Parkes radio telescope (Murriyang). This project aims to investigate the polarization and emission properties of these pulsars through detailed modeling using the rotating vector model (RVM). Polarization profiles will be obtained over a wide frequency range, from 704 MHz to 4032 MHz. We will measure the emission height differences between the main pulse (MP) and IP as a function of frequency, allowing us to explore their frequency dependence and to test the radius-to-frequency mapping (RFM) model. Spectral analyses of individual profile components will be performed to constrain the emission properties and investigate differences between the MP and IP. Additionally, we will examine quasi-periodic microstructure in both MP and IP, aiming to characterize the microstructure period and explore its potential correlation with the magnetic inclination angle. This comprehensive investigation will yield new insights into the emission geometry of pulsars with IP emissions, contributing to a better understanding of their unique characteristics within the pulsar population.
