• Asymptotic theory of resonant tunneling in quantum waveguides of variable cross-section 

  Sarafanov, Oleg (University of Jyväskylä, 2008)

  Halkaisijaltaan muunnellun kvanttiaaltojohtimen kapenemat toimivat tehokkaina potentiaalivalleina elektronin pitkittäissuuntaiselle liikkeelle. Kaksi kapenemaa muodostaa kvanttiresonaattorin, jossa resonoiva tunnelointi ...

• Electromagnetic wave propagation in non-homogeneous waveguides 

  Poretskii, Aleksandr (University of Jyväskylä, 2015)

  We investigate an electromagnetic waveguide, having several cylindrical ends. The waveguide is assumed to be empty and to have a perfectly conductive boundary. We study the electromagnetic field, excited in the waveguide ...

• The role of radio frequency scattering in high-energy electron losses from minimum-B ECR ion source 

  Izotov, Ivan; Shalashov, Alexander G; Skalyga, Vadim; Gospodchikov, Egor D; Tarvainen, Olli; Mironov, Vladimir; Koivisto, Hannu; Kronholm, Risto; Toivanen, Ville; Subhash Bhasi Bhaskar, Bichu (IOP Publishing, 2021)

  The measurement of the axially lost electron energy distribution escaping from a minimum-B electron cyclotron resonance ion source in the range of 4--800 keV is reported. The experiments have revealed the existence of a ...

• Spatial localization of hotspots in Fano-resonant plasmonic oligomers for surface-enhanced coherent anti-Stokes Raman scattering 

  Dutta, Arpan; Vartiainen, Erik M. (Springer, 2020)

  Realization of Fano resonance in plasmonic oligomers is often exploited to design efficient plasmonic substrates for surface-enhanced coherent anti-Stokes Raman scattering. Disk-type Fano-resonant plasmonic oligomers are ...

• Massless positivity in graviton exchange 

  Herrero-Valea, Mario; Santos-Garcia, Raquel; Tokareva, Anna (American Physical Society (APS), 2021)

  We formulate positivity bounds for scattering amplitudes including exchange of massless particles. We generalize the standard construction through dispersion relations to include the presence of a branch cut along the real ...
