1-Admimistering Metamaterial into Electromagnetic Absorber and AMC Reflector for Size Reduction and Performance Enhacement

With current trend and fast growth in electronics, portability has become critical. Furthermore, the discovery and development in nano-transistors pushed the need for portability to the highest limit. With this development, Electronics components or devices to be integrated into such tiny devices also need to be much smaller. Narrowing down to devices backboned by absorbers and for applications such as sensors, photo detectors, infrared camouflage, wireless communication, thermo photovoltaics, solar photovoltaics, low profiling antennas, remote sensing etc. Thus as mentioned earlier, these absorbers and reflectors to be integrated into these devices need to be smaller so as to fit in. On the other side metamaterial are artificially created materials purposely engineered to have properties that may not exist or be found in nature. These properties vary in different ways depending on the applications to be used. These properties contribute greatly towards structure compactness / size reductions, enhancement of radiation patterns and reduction of back loops etc. Although metamaterials are characterized by narrow bandwidth which is considered to be one of their drawbacks, yet their profits/benefits outweigh their drawbacks. In the case of absorber designs, it capitalizes on this drawback to maximize absorption. Imagine having the structures used in above mentioned applications to be redesigned or reinvented using metamaterials to inject those unusual properties which in turn, reduces the size and increases compactness and portability, increases or enhances overall performance such as radiation, absorption etc. and yet remain even smaller than initial design with low profile.
