    "abstract": "We analyse the optical (or microwave) tunnelling properties of\nelectromagnetic waves passing through thin films presenting a specific index\nprofile providing a cut-off frequency, when they are used below this frequency.\nWe show that contrary to the usual case of a square index profile, where\ntunnelling is accompanied with a strong attenuation of the wave due to\nreflection, such films present the possibility of a reflectionless tunnelling,\nwhere the incoming intensity is totally transmitted.",
