Nickel ferrite/Chitosan composite as a RADAR absorbing material on missile: A review and prospective

Abstract

Missiles are usually difficult to attack a land target or a surface ship that is equipped with a RADAR. Therefore, technology needs to be developed on missiles so that they are not detected by enemy RADAR. One of these technologies is the provision of RADAR absorbing material on missiles. Nickel ferrite is a cheap material that has high permeability, high resistivity, and high magnetic saturation, so it can be used as RADAR absorbing material. Chitosan is a biopolymer that is polycationic or possessing lots of positive charges from the nitrogen group. These polycationic properties tend to classify chitosan into dielectric materials. Materials with high dielectric properties will be able to absorb electromagnetic waves. Nickel ferrite and Chitosan are combined to make a cheap composite and has a prospect to be a RADAR absorbing material on missile.
