![]() We believe that our results can be used as practical guidelines for realization of efficient broadband infrared absorbers of subwavelength sizes desirable in diverse applications. Relations to effective medium parameters obtained by the internal homogenization are established and discussed. We obtain simple analytical expressions for the absorption resonances in spherical and cylindrical configurations that allow one to quickly identify the configuration parameters ensuring strong infrared absorption in a given spectral range. Analyzing in detail spherical and cylindrical core-shell nanostructures, we demonstrate that the resonant infrared absorption can be not only very efficient, i.e., with the absorption cross sections exceeding geometrical ones, but also broadband with the spectral width being of the order of the resonant wavelength. Realizing that nanostructures would efficiently absorb radiation only when their dielectric properties match those of the environment and making use of the effective medium approach, we develop the design strategy using core-shell nanostructures with very thin shells made of poor metals, i.e., metals having real and imaginary parts of their dielectric permittivities of the same order of magnitude. ![]() We suggest to exploit dielectric-metal core-shell nanostructures for efficient resonant and yet broadband absorption of infrared radiation with deeply subwavelength configurations. Note: Author names will be searched in the keywords field, also, but that may find papers where the person is mentioned, rather than papers they authored.Use a comma to separate multiple people: J Smith, RL Jones, Macarthur.Use these formats for best results: Smith or J Smith In this paper it is shown that the enhancement factor of the local electric field in metal covered ellipsoidal nanoparticles embedded in a dielectric host.For best results, use the separate Authors field to search for author names. When a cylindrical shell is filled with a soft core, i.e.We propose the approach for calculation of electron subbands in cylindrical CMS NWs within the simple effective mass approximation. Use quotation marks " " around specific phrases where you want the entire phrase only. Analysis of axisymmetrical motions of cylindrical shells by the method of characteristics. Abstract The recent advances in nanowire (NW) growth technology have made possible the growth of more complex structures such as core-multi-shell (CMS) NWs.Question mark (?) - Example: "gr?y" retrieves documents containing "grey" or "gray".Asterisk ( * ) - Example: "elect*" retrieves documents containing "electron," "electronic," and "electricity".Improve efficiency in your search by using wildcards.Example: (photons AND downconversion) - pump. ![]() The IC method can be exploited very conveniently for this system. Example: (diode OR solid-state) AND laser Note that the Green’s function, G (r, r) rr, is the potential due to a charge located at r.Note the Boolean sign must be in upper-case. Separate search groups with parentheses and Booleans.Keep it simple - don't use too many different parameters.
