Such microbunching effect can be both beneficial and detrimental, from which this effect can enhance the coherent radiation, it may also lead to a degradation in the overall quality of the bunch. Therefore, it is necessary to gain a deeper understanding of the dynamical processes involved in order to effectively suppress or manipulate the electron bunch during beam transport. In this presentation we provide a brief overview of typical theoretical models and their assumptions, discussing the collective dynamics of the phase space for different bunch configurations. Preliminary numerical results are presented for several different lattice designs and various bunch configurations, with the aim of providing theoretical guidance for the design of different types of accelerator beam transport lattices in the future.
