NGC1068 reveals a complex structure of the dust within the inner tens of parsecs, when using N- and Q-band ground-based spectra, that cannot be easily reproduced with a simple dusty model ([Pasetto+19]). We plan to study how to explain this behavior developing new SED models. Furthermore, we plan to study whether the complex behavior of dust seen in NGC1068 is also seen in other AGN. For this purpose we have been granted with new Q-band observations for 10 AGN with available N-band.
