Stockman&#39\;s publication of his landmark paper\n“communications by means of reflected waves” and L.

Its implementation for traceabili ty and identification is enjoying\nremarkable success in many applications . Today\, RFID is a major technology for the implementation\nof IoT and fo r enabling Artificial Intelligence. In practice\, RFID tags are used to id entify and locate the\ncomponents of a physical system. Reading all the ta gs in a given system allows it to be associated\nwith a digital model in c yberspace. Thus\, RFID bridges the gap between the physical and cyber\nwor lds. This keynote\, organized in 4 sections\, will discuss the state of th e art of RFID and its\napplications for identification\, communication and sensing.\n The first section will introduce the Backscatter phenomena in RF technologies\, in particular\nRadar\, Scattering\, and more recently in RFIDs. Early work on backscatter is the landmark paper\nof H. Stockman will be pointed out. The Radar Cross Section (RCS) parameter will also be \ndiscussed and how it is exploited for RFID systems. Then the history of backscatter and the\ntheory behind its physics will be reviewed. Several e xamples of its exploitation for wireless\ncommunication and sensing will b e discussed\n In the second section RFID system components will be disc ussed along with their classification.\nThe most emblematic component of R FID is the tag that stores the information and responds to\nthe RFID reade r when interrogated. Tags are very compact devices\, composed of an Integr ated\nCircuit (IC) connected to an antenna. They are typically passive dev ices empowered by the\ninterrogation signal generated by the RFID Reader. The operation of tags will be discussed along\nwith design approaches\, in particular the antenna design and the modulation of backscatter\nsignals. A survey of tag categories\, their performance\, existing applications\, evolutions and\nchallenges will be included in this section of the course. \n The third section is dedicated to chipless technology. How the Infor mation can be encoded in\nthe tag\, without the support of an Integrated C ircuit (IC)\, will be addressed along with different\nsolutions will be pr esented in detail and discussed. A survey of potential applications of thi s\ntechnology and challenges will also be addressed.\n The fourth secti on is dedicated to sensor device and how sensing capabilities can be gener ated\nin Chipless devices. A brief review for the main features of a senso r and their characterization\nwill be provided.
