Decibel attenuation of a microwave oven wall. Repeat the previous MATLAB exercise but for the 1-mm thick stainless steel (σ = 1.2 MS/m, μ_r = 500, and ε_r = 1) wall of a microwave oven, and frequencies f₁ = 2 GHz, f₂ = 2.2 GHz, f₃ = 2.45 GHz (standard frequency for microwave cooking), f₄ = 2.7 GHz, and f₅ = 3 GHz. In addition to f and A_dB, calculate and print-to-file (to file microwave.txt) the one-percent depth of penetration (δ_1%) into the wall as well, where δ1% is defined as the depth into a conductor at which the electric field intensity decreases to 1% of the initial value and it comes out to be δ_1% = δ ln 100 ≈ 4.6 δ [δ is given by the first expression in Eqs.(7.20)].
