Excitation procedure in metamaterial becomes complex accompanied with the metamaterial design evolving from the simple uniform single layer metallic patterns to ordered or multilayer metallic patterns. This paper describes the excitation procedure in multilayer metamaterial, associated with the electromagnetic wave tunneling effect. Metamaterial of single-layer split ring resonator (SRR) has low transmission (or forbidden status) on the incoming electromagnetic wave at its resonance. However, when the SRR is sandwiched by a pair of metallic patterns, it shows improved transmission, which can be explained by electromagnetic wave tunneling effect. This finding has benefits to optical components design with metamaterials by considering the electromagnetic compatibility.
