In the field of wireless communication, the spectrum (i.e., the radio frequency that supports devices to communicate through space propagation) is very important. However, like all resources, wireless networks are becoming overcrowded due to the proliferation of connected devices and increased data rates. With the continued construction of 5G infrastructure and the introduction of 6G technology, the problem is expected to become more serious.

According to foreign media reports, Cristian Cassella, associate professor of electronic and computer engineering at Northeastern University in the United States, and his team have developed new MEMS using metamaterials (engineering materials that do not exist in nature), which is expected to become a key breakthrough in dealing with network congestion.
