In this paper, UNIPIC code, a new member in the family of fully electromagnetic particle-in-
cell (PIC) codes for simulations of high power microwave (HPM) generation, is introduced. In …

This paper introduces a self-developed, three-dimensional parallel fully electromagnetic
particle simulation code UNIPIC-3D. In this code, the electromagnetic fields are updated …

A dispersive hybrid implicit–explicit finite-difference time-domain (HIE-FDTD) method is

A hybrid implicit explicit-finite difference time-domain (HIE-FDTD) method is proposed to
simulate a graphene-coated shielding sheet. In this method, both the interband and …

Preliminary experimental results of a repetitive 0.14 THz overmoded relativistic surface wave
oscillator (RSWO) are presented in this paper. The repetitive RSWO is developed by using a …
