Development of Metamaterial-Inspired Vacuum Electron Devices: An Emerging Research Direction of Vacuum Electronics
Abstract
Metamaterials are artificially constructed subwavelength structures that have exotic physical properties that cannot be realized or are difficult to realize with natural materials. Hence, the creative introduction of metamaterials into vacuum electron devices (VEDs) has led to their novel performance with characteristics such as small size, low weight, high power, high efficiency, or high gain. The use of transformative technologies will facilitate their development from laboratory demonstrations to industrial deployment.
