**4.1 Optical transmission of 1D PC without defects**

In these experiments the thickness of the layers were kept comstant - *dA* =24mm and *dB* =6mm - and the frequency varied ω∈(0,9)*GHz.* As it is specified earlier there will be two cases: case 1 in which A is a dielectric material and case 2 in which A is an epsilon negative material. In both cases B is a double negative material (Ramakrishna, 2005).
