Multiwall carbon nanotube enhance the invisibility effect from radar

open access: yesResults in Physics, 2020
The shape and size do not always give us the desired result of low cross-section on the radar of observable specifications. Nowadays, to improve lower radar cross-section, most of the country is using radar-absorbing materials, in addition to the shape ...
