Resonance scattering in a waveguide with identical thick perforated barriers
作者：
Highlights：
• We study wave propagation in a waveguide blocked by two perforated thick barriers.
• For small holes, waves over a broad range of frequencies are almost fully reflected.
• However, there is a resonance frequency at which the wave is almost fully transmitted.
• An explicit equation that determines the resonance frequency is derived.
• The proof is constructive, uses elementary tools and is educationally appealing.
