Implementation of Differential and Integral Operators in Analog Optical Computing چكيده انگليسي Arefeh Nikdast a nikdast@ec iut ac ir August 1 2020 Department of Electrical Engineering Isfahan University of Technology Isfahan 84156 83111 Iran Degree Master of Science Language Farsi Supervisor Masood Omoomi Assist Prof omoomi@cc iut ac irAbstractAs the applications of optical systems are developed in recent years especially in the field of communication optical analog computing considered one of the most prominent and growing topics Although most datacomputing is still digital analog optical computing can overcome multiple drawbacks followed by their digitalcounterparts such as algorithm complexities data classification compression and conversion difficulties Furthermore analog optical computing systems provide real time ultrafast and parallel optical computing andencryption In general analog optical computing can be performed in two spatial or temporal domains Conventional lens based spatial analog computing requires bulky systems that cannot be used in opticalintegrated circuits to form an all optical system The concept of computational metamaterials has beenintroduced to perform spatial analog computing on the sub wavelength scale Such materials are designed tomanipulate the impinging field so that the reflected or transmitted field is proportional to the field calculatedby performing the desired mathematical operation on the impinging field Two different methods named metasurface MS approach and Green s function GF approach can be used to design such structures Inthis thesis based on the GF approach the desired mathematical operator is implemented directly in the Fourierdomain This research goes beyond substantial limitations imposed by previous studies by introducing twoframeworks These restrictions include operating only at reflection mode implementing only even Green sfunctions and most importantly executing only a single operator First the multilayer structure is designedbased on the transmission line model This structure unlike previous similar structures can simultaneouslyimplement two operators in reflection or transmission mode In the next approach a metasurface is designedthat in addition to implementing multiple operators at the same time can also implement even Green sfunctions at the normal incident by eliminating structural symmetry KeywordsAnalog computing Spatial analog optical computing Green s function approach Computationalmetamaterial Metasurface Angular scattering Transmission line model Multilayer computer
