We have experimentally studied emission of microwave radiation from a monopole source embedded in a three-dimensional photonic crystal. We have demonstrated enhancement of microwave radiation at the band edge and cavity mode frequencies. Furthermore, we have shown that it is possible to obtain highly directive microwave radiation sources operating at the band edge of the three-dimensional photonic crystal. We have measured half power beam widths of 13 degrees for both E and H planes, corresponding to a maximum directivity of 245.
我们通过实验研究了嵌入三维光子晶体中的单极源的微波辐射发射。我们已经证明了在带边和腔模频率处微波辐射的增强。此外，我们已经表明，有可能获得在三维光子晶体带边工作的高指向性微波辐射源。我们测量了E平面和H平面的半功率波束宽度均为13度，对应于245的最大方向性。
