An EMI analysis modelling method for electro-optical/infrared systems

Electromagnetic interference/electromagnetic compatibility (EMI/EMC) prediction models and techniques, and analysis tools are being widely developed and used for radio frequency systems. However, given that electro optical (EO) and infrared (IR) systems also utilise the electromagnetic spectrum, it is important that the EMI/EMC concept should also be extended to incorporate EO and IR systems. There are currently no prediction models and technique or analysis tools available to assess EMI/EMC of EO and IR systems. This paper presents an EMI/EMC modelling prediction method, which has been applied on a number of test cases to assess EMI/EMC for EO and IR systems.
