Thermocouple sensor :

  • A thermocouple sensor is a junction of two dissimilar metals or semiconductors. 
  • It generates an emf when two ends are heated up differently by absorption of microwaves in a thin film tantalum– nitride resistive load deposited on a Si substrate which forms one electrode of the thermocouple. 
  • This emf is proportional to the incident microwave power to be measured.
