 atical methods are fundamental tools
  in Electrical and Computer Engineer
 ing, as they enable the understandin
 g and prediction of complex physical
  phenomena and provide effective too
 ls for the analysis and design of mo
 dern technological systems. This tal
 k presents representative problems i
 n electromagnetic propagation, scatt
 ering, and waveguiding, highlighting
  how mathematical modeling connects 
 fundamental theory with real-world a
 pplications in Electrical and Comput
 er Engineering and industry.\n The t
 alk first considers the transfer of 
 electromagnetic energy in urban envi
 ronments in the presence of obstacle
 s and corners, a problem of particul
 ar importance for current and future
  wireless networks. The possibility 
 of guiding surface waves around corn
 ers by means of appropriately design
 ed intelligent electromagnetic surfa
 ces is investigated, with the aim of
  maintaining communication even when
  a direct line of sight between tran
 smitter and receiver is unavailable.
 \n PTD-symmetric waveguides are then
  presented, enabling the propagation
  of a strongly localized electromagn
 etic mode along the interface betwee
 n two surfaces. Energy—and therefore
  information—is transported along th
 e interface, while the electromagnet
 ic field decays strongly in the tran
 sverse direction. This property enab
 les propagation that is protected ag
 ainst backscattering and reflections
 . The study is extended from ideal t
 heoretical structures to realistic B
 ed-of-Nails metasurfaces (periodic m
 etallic pins), thereby connecting ma
 thematical modeling with practically
  realizable waveguiding structures.\
 n The interaction and scattering of 
 electromagnetic waves by coupled die
 lectric scatterers are also examined
 , with the aim of understanding and 
 controlling coupling and radiation d
 irectionality, properties of importa
 nce for photonic devices, optical an
 tennas, and metamaterials. Anisotrop
 ic plasma structures are further con
 sidered, as they can support control
 led and nonreciprocal propagation an
 d radiation, with applications in mi
 crowave technology and the THz frequ
 ency range.\n Finally, mathematical 
 modeling is applied to biomedical pr
 oblems in order to understand how el
 ectromagnetic waves transfer energy 
 into and out of biological tissues. 
 This analysis is important for wirel
 ess communication with implantable m
 edical devices, a key application ar
 ea of advanced Body Area Network tec
 hnologies.\n Overall, the talk highl
 ights the role of Mathematical Metho
 ds in Electrical and Computer Engine
 ering as a bridge between fundamenta
 l theory and the design of modern te
 chnological systems.\n \n About the 
 Speaker\n Xenofon M. Mitsalas is an 
 Electrical and Computer Engineer spe
 cializing in mathematical and semi-a
 nalytical methods in applied electro
 magnetics. He graduated first in his
  class from the Department of Electr
 ical and Computer Engineering at Dem
 ocritus University of Thrace and rec
 eived his Ph.D. from the same Depart
 ment with Honors.\n His doctoral res
 earch focused on the development of 
 analytical Wiener–Hopf methods for c
 omplex wave-propagation and radiatio
 n problems, including the factorizat
 ion of non-symmetric and non-meromor
 phic kernel functions in anisotropic
  media and the analytical study of s
 urface and leaky waves.\n From 2022 
 to 2023, he worked as a postdoctoral
  researcher at the University of Bre
 scia. Since 2023, he has been conduc
 ting research at the Department of I
 nformation Engineering and Mathemati
 cal Sciences of the University of Si
 ena under the supervision of Profess
 or Stefano Maci. His recent research
  focuses on the development of exact
  and semi-analytical methods for PTD
 -symmetric waveguides, metasurfaces,
  Bed-of-Nails structures, and proble
 ms involving diffraction and surface
 -wave propagation.\n His research ha
 s led to original analytical solutio
 ns and publications in leading inter
 national journals, including IEEE Tr
 ansactions on Antennas and Propagati
 on and IEEE Open Journal on Antennas
  and Propagation. He has also presen
 ted his research at major internatio
 nal conferences, including EuCAP, IE
 EE AP-S/URSI, ICEAA, IEEE ACES, AES,
  and URSI EMTS.\n He also serves as 
 a reviewer for IEEE Transactions on 
 Antennas and Propagation (TAP) and I
 EEE Open Journal on Antennas and Pro
 pagation (OJAP).\n His main research
  interests include mathematical meth
 ods in electrical engineering, the W
 iener–Hopf method, complex analysis,
  the Sommerfeld–Malyuzhinets method,
  waveguide theory, surface and leaky
  waves, electromagnetic diffraction,
  and metasurfaces.\n
