Electromagnetic Interference (EMI)
Unwanted electronic noise/ interference
Caused by either EM Induction/ EM Radiation
EMI involves a Source, Path & Victim
EMI Shielding Mechanism
Minimize EM radiations
Reflection
Absorption
Transmission
Multiple Internal Reflection
Prevent penetration of EM radiation
Create barrier against EM radiations
Shielding Materials Used
Metals
Drawback in metals restrict their use
Initially used shielding materials
Scatter EM radiations
Caused secondary pollution
Nanocomposites
Nanocomposites replaces metals
Having Unique properties
Absorb max EM radiations
Avoid secondary electronic pollution
