Using the Finite Difference Frequency Domain (FDFD) method, the study revealed that introducing two defect layers\u2014one metal and one sensing material\u2014produces a double resonance effect with high sensitivity, significantly surpassing single resonance designs.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The presence of a metal defect layer generates a surface plasmon resonance (SPR) phenomenon, which enhances light transmission and sensitivity. This breakthrough allows resonance peaks to be finely tuned by adjusting the thickness and refractive index of the defect layers, offering a promising foundation for developing next-generation optical and biosensors. Such devices have potential applications in medical diagnostics, environmental monitoring, and advanced communication systems.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This research contributes to the UN Sustainable Development Goals (SDGs) 9: Industry, Innovation, and Infrastructure, and 12: Responsible Consumption and Production, by enabling innovative sensor technologies that are more efficient, precise, and adaptable for sustainable development.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Full article:<a href=\"https:\/\/doi.org\/10.37934\/araset.44.2.175183\"> Double Resonance Characteristic of Photonic Crystal Structure with Defect Metal Layer<\/a><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Meet the Researchers:<br \/>This study was conducted by <strong>Teguh Puja Negara, Sudradjat Supian, Subiyanto, and Mohd Kamarulzaki Mustafa<\/strong> from Universitas Pakuan, Universitas Padjadjaran, and Universiti Tun Hussein Onn Malaysia.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<p class=\"wp-block-paragraph\">Hashtags:<br \/>#Photonics #OpticalSensors #Innovation #SDG9 #SDG12 #UnpadResearch #Nanotechnology<\/p>","protected":false},"excerpt":{"rendered":"<p>A team of researchers from Universitas Padjadjaran, Universitas Pakuan, and Universiti Tun Hussein Onn Malaysia has successfully analyzed the double resonance characteristics of photonic crystal structures with defect metal layers.
