Experimental reasearch on X-band high power microwave radome composed of left-handed materials

To improve the performance of high power microwave (HPM) antennas, a novel X-band left-handed material planar radome is developed. The measurement results of this radome show that the beam of a antenna can be focused by using the left-handed material radome with 1-4 layers in the frequency range of 9.0-9.4 GHz, and the gain of the antenna can be raised by about 9.64 dB at 9.32 GHz for the radome with one layer. But the experimental data do not agree well with the theoretical simulation. The analysis of the power capacity of the radome indicates that the radome could be applied to HPM field.
