Abstract: The last decade has witnessed extensive research ef-forts to reduce the size of charged particle accelerators toachieve compact devices for providing relativistic particles.To this end, various methods such as laser plasma and di-electric wakefield acceleration are investigated and theirpros and cons are studied. With the advent of efficient THzgeneration techniques based on optical rectification, THzwaveguides are also considered to be proper candidatesfor compact accelerators. Sofar, the proposed schemes to-ward high power THz generation are capable of produc-ing short pulses, which dictates the study of particle accel-eration in the pulsed regime rather than continuous-waveregime. Therefore, THz waveguides are more suitable thancavities for the considered purpose. Consequently, variouseffects such as group velocity mismatch and group veloc-ity dispersion start to influence the acceleration scenarioand impose limits on the maximum energy gain from thepulse. In this contribution, we investigate electron bunchacceleration and compression in dielectrically loaded metalwaveguides for the THz wavelength range and present de-sign methodologies to optimize their performance
