Electromagnetic functional materials 2Asst.Professor,
Nobody can think about a world without modern technologies. With the use of most modern electronic equipments, harmful electromagnetic radiations are rapidly increasing to a rate that we can’t even imagine. These radiations are harmful to both human beings and environment. To protect our health and environment from these serious electromagnetic radiation, electromagnetic functional material become an inevitable requirement of the society. Electro Magnetic wave absorbing materials has great significant in present scenario. In this research paper ferrite is used as chief EM functional material along with different green material especially waste material. Absorption performance of different composition of materials with different thickness range is tested in 1-8GHz frequency range. To create a sustainable future and pollution free environment different green materials and their electromagnetic absorption capacity is analyzed.
The EM functional materials with attenuation effect on EM waves are usually divided into EM wave absorbing materials and electromagnetic interference (EMI) shielding materials.[1] 2.1 EMI shielding materials EMI shielding materials can separate the two regions and control the induction and radiation of electric fields, magnetic fields, and EM waves from one region to the other. Both reflection and absorption in EMI shielding materials will contribute greatly to excellent EMI shielding. However, based on the pursuit of the green shielding concept, the ideal EMI shielding requires low reflection and strong absorption.[1]
Key Words: Electro Magnetic (EM) Radiation, Green

Materials, Reflection Loss, Ferrite, Sustainability
EM wave absorbing material refers to a class of materials that can absorb EM waves energy projected onto its surface.[1]
1. INTRODUCTION Most modern world is filled with most modern electronic reequipments’ are living in a digital era, highly anticipated electronic equipment are widely using everywhere. They become an inevitable part of our day-to-day life. Due to this widespread use of electronic equipment having heavy frequency range EM radiation is increasing to an unimaginable rate. These harmful radiations are affecting human health and environment. Living in a healthy pollution free environment is like a dream today. Building materials having the capacity to absorb this harmful EM radiation have great importance in current society.
3. DESIGN PRINCIPLE An incident EM wave through EM absorbing material undergoes three processes: reflection, absorption and penetration, as shown in Fig. 1. EM wave absorption is a process, in which the EM energy will be transformed into other forms energy under the action of EM loss fillers, so that the incident wave cannot be reflected or permeated through the materials [2,4]
In the present scenario green buildings become the Centre of attraction of the construction industry. People are showing more interest towards green buildings and green materials in order to achieve safe and sound living. 1.1 Electro Magnetic Interference (EMI) The disruption caused by EMWs in another electronic device, causing the second device to malfunction is known as the electromagnetic interference (EMI) [7–12]
