What outcome occurs when transmitting radio wave through Faraday cage with overly large apertures?

💡 Explanation

When a radio wave encounters apertures larger than a fraction of its wavelength, diffraction occurs because the EM wave bends and propagates through the opening rather than being fully blocked, causing signal leakage. Therefore signal leakage through diffraction results, rather than internal amplification, absorption heating, or simple reflection, which require different aperture constraints.
