In this talk, we will review the contribution of Prof. Mario Sorolla to the field of artificial materials, highlighting several of his research milestones in metamaterials. We will cover his contributions to one dimensional metamaterial designs, mainly in microwave planar circuit technology. Additionally, his work on two- and three dimensional metamaterial structures will be presented, with particular emphasis on quasioptical structures like prisms, lenses, polarizers, etc. His last contributions to the field of terahertz (THz) waves will be shown.
