Abstract
Transmission and reflection spectra of resonant metallic filters fabricated by the laser direct writing technique were investigated in terahertz frequency range. Effect of thin dielectric layer on surface waves excitation was observed as a larger redshift of the transmittance peak dependent of dielectric film thickness and metal film surface smoothness.
