Abstract :
A microwave field-detecting element based on the pyroelectric effect in polyvinylidene fluoride (PVDF) has been developed. Characterisation of the response of a half-wavelength structure etched on 25 ¿m PVDF film has been modelled and validated by measurements. The sensitivity, linearity and dynamic range are sufficient for array applications.
