Smart EMI vent

An EMI shielding system comprising:

• an EMI shielded vent panel for disposition over a corresponding opening in an electronics enclosure, the vent panel comprising an electrically conductive medium having a plurality of cells which define a plurality of ventilation passageways, each passageway including an entry and a channel connected to and extending away from the entry, wherein each passageway is selectively actuated between at least a first constricted state and a second deconstricted state upon application of or removal of an activation mechanism;
• a receiver configured to monitor EMI energy radiating into and out of the electronics enclosure;
• a thermocouple configured to monitor the temperature inside the electronic enclosure;
• and
• a controller configured to modulate the effective size of the entry of each passageway based on input received from the receiver and the thermocouple.
