Energy direction is a function of frequency in low pass 2D lattice at frequencies close to the cut off. This property can be used to implement a high quality factor filter called electrical prism. Negative effective index was also shown to be achievable using the structure. Channeling of the signal and spatial filtering are the main reasons behind the filter having higher quality factor than component quality factor. This structure is specially interesting as it is easy to fabricate on conventional CMOS process.
