Experimental realization of an open cavity
2014 (English)In: Scientific Reports, ISSN 2045-2322, Vol. 4, 5965- p.Article in journal (Refereed) Published
The design and experimental demonstration of an open cavity in the microwave region is presented. The resonance condition is achieved through the cancellation of lightpaths in positive and negative refractive index materials. The positive index material is a structured aluminium surface supporting a spoof surface plasmon mode, and the negative index material is a photonic crystal made of alumina. A resonance peak is observed in the measured spectrum at which the electric field distribution agrees with numerical simulation.
