Abstract
The aim of this paper is to suggest performance improvements in an A6 relativistic magnetron (RM) using the particle-in-cell (PIC), finite difference time domain (FDTD) simulation tool. It is shown that adding conductive strappings to the resonator assists in improving π-mode performance of the device by modulating the beam velocity profile. Comparisons have been made between the performance variables of a strapped and an unstrapped relativistic magnetron. In addition, the tapered mode converting structures are investigated which also assist in the π-mode performance of the RM. Also, a review is made on the basic operation of the RM with elements from both circuit and field theory.

Summary
The objective of this paper is to study and simulate relativistic magnetron (RM) which is a high-power microwave (HPM) generating source. A Magnetron oscillator is a cross-field device which can generate microwaves in an approximate frequency range of 1-10 GHz. The conventional magnetrons operating at low voltages (
