    "abstract": "Since the discovery of backward-wave materials, people have tried to realize\nstrong chiral medium, which is traditionally thought impossible mainly for the\nreason of energy and spatial dispersion. We compare the two most popular\ndescriptions of chiral medium. After analyzing several possible reasons for the\ntraditional restriction, we show that strong chirality parameter leads to\npositive energy without any frequency-band limitation in the weak spatial\ndispersion. Moreover, strong chirality does not result in a strong spatial\ndispersion, which occurs only around the traditional limit point. For strong\nspatial dispersion where higher-order terms of spatial dispersion need to be\nconsidered, the energy conversation is also valid. Finally, we show that strong\nchirality need to be realized from the conjugated type of spatial dispersion.",
