This paper investigates the beamforming design for secure transmission in multiple-input multiple-output (MIMO) communication systems with simultaneous wireless information and power transfer (SWIPT), where the energy harvesting (EH) receivers  may eavesdrop the confidential information send to the information decode (ID) receiver. To solve the non-convex problem, we propose a simple solution, which is to chose a beamforming matrix part first, then find the rest of the beamforming matrix by solving the convex problem. Finally, numerical results are provided to validate our proposed algorithm.
