La donna fantasma : immagini del petrarchismo filmico
No full textAnche se la forza e la vastità delle influenze petrarchesche nel cinema debbono talvolta essere cercate e trovate con la pazienza certosina dell'entomologo o dello studioso di metafore, Gino Frezza rintraccia significative e ineludibili presenze delle figure poetiche petrarchesche nella tradizione filmica del cinema classico e in quello moderno e contemporaneo. Il rapporto fra l'opera di Petrarca e il cinema si rivela, seppure in filigrana, nella cruciale, enigmatica, valenza di un crocevia culturale non secondario, ricorrente, denso di sorprese. Prima Frezza ripercorre come Petrarca, nelle rime del Canzoniere, trama la difficile, complessa, interfaccia fra rima e immagine, dimensione della scrittura e configurazione visiva, e come, per tale interfaccia, si imponga la figura della Donna nei termini di una immagine ad alto coefficiente fantasmatico. Poi l'autore illustra la permanenza dei temi poetici del Petrarca in un ambito di produzioni filmiche appartenenti ad autori ed epoche del Novecento che, con l'opera del poeta italiano, non hanno rapporti espliciti né affiliazioni o vicinanze metaforiche. Ecco dunque la «donna fantasma» petrarchesca trasformarsi nelle fisionomie filmiche della donna-quadro e della donna-specchio, della donna-statua, della donna-ricordo e, infine, della donna-idea. L'analisi delle influenze petrarchesche nel cinema si conclude ascrivendo al poeta italiano trecentesco l'origine più lucidamente consapevole di una teoria delle lacrime, che non a caso e molto spesso coprono d'improvviso gli occhi degli spettatori di cinema. Le lacrime spettatoriali -una esperienza insieme fisica e lirica, manifesta e intima- corrispondono alle lagrime petrarchesche, a fronte della vanità terrena dei mortali.The strength and magnitude of Petrarch's influence on cinema must sometimes be sought out with the Carthusian patience of the entomologist or like the study of metaphors. Nevertheless, Gino Frezza retraces the significant and unavoidable presence of Petrarchan poetic figures in the film tradition of both classic and modern, contemporary cinema. The connection between the work of Petrarch and the cinema is revealed, though delicately, in the crucial, enigmatic strength of an early, recurrent cultural crossroads, thick with surprise. Like Petrarch, Frezza first retraces the rhymes of the Canzoniere, plotting the difficult, complex interface between rhyme and image, the dimensions of writing and visual configuration, and how, for such interface, the figure of the Woman was imposed as a highly ghost representation. The author then illustrates the continuity of Petrarch's poetic themes in a film production environment pertinent to authors and periods from the 10th Century which, with the work of the Italian poet, bore no explicit relation nor metaphoric affiliation or similarity. It was here, therefore, that the Petrarchan «ghost woman» was transformed into the cinematic physiognomies of the portrait-woman, mirror-woman, statue-woman, memory-woman and, finally, the idea-woman. The analysis of Petrarchan influences on cinema is concluded by crediting the 4th Century Italian poet with the most lucidly conscious origin of a theory of tears, which very often, and not unintentionally, covers the eyes of cinema audiences. Spectator tears -an experience both physical and lyrical, open yet intimate- are significant of Petrarchan tears, relating to the earthly pride of mortals

A spectral-domain method for the electromagnetic scattering from a multilayered sphere buried in a stratified medium
No full textIn this work we present a rigorous method to analyze the electromagnetic scattering of an elliptically polarized plane wave by a multilayered sphere buried in a dielectric stratified medium (Fig. 1). The interaction of the electromagnetic radiation with the stratified material is taken into account by means of the transfer-matrix approach: in this way we can consider the stratified medium as an effective single interface. We assume that all media are linear and lossless

No full textThis project aims to develop and validate innovative methods for the
analysis and synthesis of intelligent surfaces and metamaterials, with
special emphasis on electromagnetic and audio waves. The objectives
of the project include the study of existing methods, the formulation of
new solutions and the comparison in terms of performance. Special
emphasis will be placed on the use of artificial intelligence in these highly
innovative fields, including methods based on deep learning.
Metamaterials are designed to manipulate electromagnetic waves,
sound waves, or other physical phenomena in ways that traditional
materials cannot achieve. The applications range from invisibility cloaks
to advanced lensing systems, and they could be used in various
industries, including telecommunications, optics, audio and medical
imaging
