With the development of the electrification and informationization

all kinds of electrical and electronic systems or equipment are simutaneously used in the same space more and more

and electrical and electronic systems or equipment are developed at an unprecedented rate to high frequency

high speed

high precision

high reliability

high sensitivity

high density（miniaturization and large scale integration）

high power

small signal

and complexity. So the electromagnetic compatibility（EMC） become more prominent to the communication

computer

military

and medical equipment

etc

raising a great challenge to security and effectiveness. Electromagnetic protection bionics is a potential method to solve EMC. Therefore

we review the existing methods of electromagnetic protection bionics and the future research direction of biological robustness bionic. On the basis of the nature of biological robustness

we introduce structure mechanism of the feedback

degenerate and redundancy

modularity and evolvability

and behavior mechanism of the robustness and fragility of balance

stability robustness and quality robustness. The results show that biological robustness bionics is a potential method of EMC design for electronics or electrical system

and in particular the genetic

the mutation of biological systems may suggest that the electromagnetic protection design of electronic or electrical systems should be time-varying

adaptive

and balanced. And mathematical model

network

thermodynamic

especially non-equilibrium dissipative structure are basic theory for the bionics research. Future research will focus on several topics: 1) the imitation biological robustness of the system; 2) the time-invariable of system structure and parameters; 3) the trade-off of robustness and fragility. 4) the assessment of electromagnetic by steady-state

robustness allowance and DOR.
