Abstract :
Electromagnetic Zenneck THz surface waves propagating on a bow-tie antenna are employed for time-resolved near-field imaging of subwavelength-size SrTiO3 and TiO2 particles. This approach provides high contrast, high-spatial resolution imaging through enhancing the fieldparticle interaction.
