This paper reports on the design and synthesis of tunable electromagnetic (EM) absorbers by encapsulating graphite into SiC nanowires. The hybrid nanowires with controllable dielectric and microwave absorption properties are employed for achieving tunable EM absorbers. The synthesis of the graphite/SiC hybrid nanowires was conducted by electrospinning and high temperature annealing. By simply controlling annealing temperature, the hybrid nanowires annealed at 1300 °C present a maximum reflection loss (RL) of −22 dB at 16.8 GHz with a small thickness of 1.7 mm and an effective absorption bandwidth (RL
