Default Ribbon Impedance at Frequencies Above the Audible Frequency Range

It is my understanding that the impedance of a ribbon transducer (excluding the matching transformer) is largely resistive within the audio range. Does anyone know if the impedance deviates from a pure resistance as the driving frequency increases towards the MHz range?

My current tweeters start to increase after 15k slight upwards tilt , before that pretty flat until resonance peak @38hz ....

Never measured past 40k
