Today's consumers demand that electronics are smaller, lighter, cheaper, more powerful, and run longer. The circuit board is also packed with a large number of electronic components, making it increasingly dense, so it is increasingly important to suppress noise radiating from the IC or cable. This type of radiated noise is difficult to predict during the design phase, so in many cases countermeasures are taken during the manufacturing phase. To address these conflicting needs, researchers need to develop new materials that miniaturize existing equipment and improve equipment efficiency. Efforts to reduce power consumption and improve device density and performance have led to research into graphene and other two-dimensional (2-D) solid and soft magnetic materials and nanoscale devices with high carrier mobility.

With the vigorous growth of applications such as 4K/8K, VR/AR, autonomous driving, robotics, and video surveillance, 5G Internet of Everything is accompanied by massive amounts of data. This data is transmitted through densely distributed small/micro base stations and Massive MIMO antennas. It manifests itself as two major features: on the one hand, Massive MIMO itself reduces transmission power consumption at the expense of higher computing costs; The small base station has a small coverage and a lower PA, which also means that the transmission power consumption is lower. On the other hand, due to the exponential increase in 5G transmission rate, 5G base stations will process massive data, and with the continuous development of 5G services, the computing power consumption of 5G BBU will gradually rise.

Currently, the total population of the planet has reached 7.5 billion. According to a United Nations study, the total population of the planet will reach 8 billion in 2030 and 10 billion in 2050. In addition, the number of people moving to cities as well as metropolitan areas is increasing. The city offers people great career prospects, a rich and colorful cultural life and a variety of leisure activities that attract many people to join them. More than half of the world's population already lives in cities, and by 2030 it will account for 60% of the world's population. Living spaces in metropolitan areas are becoming increasingly cramped. In order to maintain the smoothness and convenience of travel, the adoption of intelligent interconnection solutions and driverless solutions of the future public transport system is an indispensable and important factor for urban development.

With the advent of the 5G era, many fields and industries have also ushered in a climax because of 5G, and the technology and electronic equipment in the medical industry are also developing rapidly. Many of the original technologies caused delays due to network data transmission speed can not meet the requirements, affecting its operation, 5G in the data transmission speed of high speed, directly accelerate the development of medical equipment. At the same time, with the increasing demand for medical health, wearable medical and health devices are also increasing. These electronic devices have high requirements for heat dissipation and EMI, and need to use thermal interface materials, electromagnetic absorbing materials, conductive shielding materials and so on.

With the development of science and technology and electronic technology, especially under the concept of Industry 4.0, the intelligentization of equipment and the Internet of Everything have used a large number of electronic products on the equipment. The reliability requirements of these products are very high, and the heat dissipation requirements and EMI requirements are also very urgent.
