Which outcome occurs when microwave radiation incidents on a metallic screen with subwavelength apertures?

💡 Explanation

When microwave radiation interacts with subwavelength apertures in a metallic screen, surface plasmon resonance occurs because incident photons excite collective oscillations of electrons at the metal surface, increasing wave transmission. Therefore, induction increased transmission occurs, rather than heightened blockage, diffraction or simple guiding, which each require either different aperture sizes or lack surface resonance phenomenon.
