  • Mäkitalo, Jouni; Suuriniemi, Saku; Kauranen, Martti (2011)
    We present the frequency-domain boundary element formulation for solving surface second-harmonic generation from nanoparticles of virtually arbitrary shape and material. We use the Rao-Wilton-Glisson basis functions and ...
  • Czaplicki, Robert; Husu, Hannu; Siikanen, Roope; Mäkitalo, Jouni; Kauranen, Martti (2013)
    We prepare arrays of gold nanoparticles that include both noncentrosymmetric particles with a second-order nonlinear optical response (active particles) and centrosymmetric particles with no second-order response (passive ...
  • Mäkitalo, Jouni; Kauranen, Martti; Suuriniemi, Saku (2014)
    We present a rigorous full-wave electromagnetic approach to analyze the modes and resonances of dielectric and plasmonic nanoparticles of practically any geometry. Using boundary integral operators, we identify the resonances ...
  • Huttunen, Mikko J.; Mäkitalo, Jouni; Bautista, Godofredo; Kauranen, Martti (2012-11)
    We show that electric-dipole-allowed surface second-harmonic (SH) generation with focused Gaussian beams can be described in terms of Mietype multipolar contributions to the SH signal. In contrast to the traditional case, ...
  • Husu, Hannu; Mäkitalo, Jouni; Laukkanen, Janne; Kuittinen, Markku; Kauranen, Martti (2010)
    We present an extensive experimental and theoretical study of the particle plasmon resonances of L-shaped gold nanoparticles. For the small characteristic size of the particles, we observe more higher-order resonances than ...
  • Harra, Juha; Mäkitalo, Jouni; Siikanen, Roope; Virkki, Matti; Genty, Goery; Kobayashi, Takayoshi; Kauranen, Martti; Mäkelä, Jyrki M. (2012)
    Aerosol techniques were used to synthesize spherical and monodisperse silver nanoparticles for plasmonic materials. The particles were generated with an evaporation–condensation technique followed by size selection and ...
  • Husu, Hannu; Mäkitalo, Jouni; Siikanen, Roope; Genty, Goery; Pietarinen, Henna; Lehtolahti, Joonas; Laukkanen, Janne; Kuittinen, Markku; Kauranen, Martti (2011)
    We introduce a concept to control the spectral and dichroic properties of metamaterials. The approach is based on anisotropic metal nanoparticles and on varying their mutual orientation in a periodic lattice. Even seemingly ...
  • Rao, Satish; Huttunen, Mikko J.; Kontio, Juha M.; Mäkitalo, Jouni; Viljanen, Milla-Riina; Simonen, Janne; Kauranen, Martti; Petrov, Dmitri (2010)
    We present two silver nanocones separated by 450 nm, well beyond the typical gap spacing of coupled nanoantennas, and connected by a metal bridge to facilitate plasmonic coupling between them. The tip-enhanced Raman ...
