A unique metal-dielectric structure composed of symmetric multilayered nanocylinder is demonstrated to support unconventional superradiant and subradiant plasmon modes. Here, the twin distinctive dipole-dipole Fano resonances are observed in the structure within the visible spectrum by carefully selecting the geometrical parameters. The spectral features of these Fano resonances are controlled by changing the incident field polarization and parameters of the nanoparticle. Eventually, an RLC circuit model is proposed to reproduce the optical response of the nanostructure.

Introduction: Inadequate nutritional status in a person with HIV-AIDS (PLWHA) has a high risk of declining health in general. If a person is infected with HIV but has a good nutritional status, his immune system will be better than someone who is infected with HIV but has poor nutritional status. With good nutritional status, it can prevent HIV disease from entering the AIDS stage. Malnutrition that occurs in a person with HIV/AIDS can accelerate the progression of HIV disease and hinder treatment, thereby worsening the patient's condition. The use of Antiretroviral (ARV) has an effect that can worsen a person's condition if it is not accompanied by good nutritional intake.Methods: The method used in this study is a literature review with predetermined inclusion and exclusion criteria. Sample: The total number of samples obtained from the results of the literature review is 128 respondents. The instrument used in evaluating the research is using an instrument from The Joanna Briggs Institute (JBI). Results: Protein-energy enriched macronutrient supplementation along with ARV initiation was effective in improving physiological nutritional status and immune response in PLWHA.Conclusion: This can prevent people living with HIV from experiencing malnutrition and wasting, can restore the ideal body weight, increase and maintain the body's ability to fight various opportunistic infections, increase the effect of drugs, and can improve and improve the quality of life of PLWHA patients
