Özet

We present low-cost fabrications of inkjet-printed metamaterials that are resonating at microwave frequencies. A very low-cost setup involving commercial desktop printers loaded with silver-based inks is constructed and used to fabricate the metamaterials. We show that, despite the challenges in the low-cost fabrication processes, successful prints, and metamaterial samples can be obtained. A composite metamaterial design, which possesses a bandlimited transparency due to the induced negative refractive index, is fabricated and tested to demonstrate the feasibility of low-cost metamaterials with relatively complex geometries involving three-dimensional arrangements.
