These two susceptibilities are particular examples of a linear response function; sometimes the terms susceptibility and linear response function are used interchangeably.
- In electromagnetic compatibility (EMC), susceptibility is the sensitivity of a device's function to incoming electromagnetic interference.
- In medicine:
- Susceptible individual
- In botany, susceptibility is the extent to which a plant, vegetation complex or ecological community would suffer from a pathogen if exposed, without regard to the likelihood of exposure. It should not be confused with "vulnerability", which taken into account both the effect of exposure and the likelihood of exposure.
