SNIP measures contextual citation impact by weighting citations based on the total number of citations in a subject field.
SJR is a prestige metric based on the idea that not all citations are the same. SJR uses a similar algorithm as the Google page rank; it provides a quantitative and a qualitative measure of the journal’s impact.
The Impact Factor measures the average number of citations received in a particular year by papers published in the journal during the two preceding years.

To calculate the five year Impact Factor, citations are counted in 2014 to the previous five years and divided by the source items published in the previous five years.

This journal establishes a dedicated channel for physicists, material scientists, chemists, engineers and computer scientists who are interested in photonics and nanostructures, and especially in research related to photonic crystals, photonic band gaps and metamaterials. The Journal sheds light on the latest developments in this growing field of science that will see the emergence of faster telecommunications and ultimately computers that use light instead of electrons to connect components.
A special section on metamaterials inherits the tradition of Metamaterials journal (www.journals.elsevier.com/metamaterials) and covers a broad range of research on artificial electromagnetic materials and surfaces in microwave and optical range, including their fabrication and applications.
The Journal features mainly original research work in experiment, theory and applications. Papers suitable for publication cover topics such as:
• Theory of photonic crystals and related micro- and nanophotonic materials • Investigation and characterization of photonic crystal properties including optical nonlinearities, photonic band gap effects, spontaneous emission, etc. • Fabrication of photonic structures and devices using various methods, including lithography, self-assembly, holography, etc. • Subwavelength optics of structured materials • Metallic and metallo-dielectric photonic structures • Structures for Terahertz optics • Plasmonics • Metamaterials and left-handed metamaterials • Chiral and bianisotropic media • Periodic electromagnetic structures • Frequency selective surfaces • High-impedance surfaces • Metamaterials for antenna and circuit technology • Metamaterial-based devices • Acoustic and elastic metamaterials • Photonic crystal fibers and "holey" fibers • Micro- and nanophotonic devices such as optical waveguides, switches, lasers, and other components of optical integrated circuits • Integration of photonic crystals • Micro-optical-electro-mechanical-systems (MOEMS) • Optical microcavities and photonic "dots" • Novel approaches to micro- and nanophotonics • Critical assessment of new application fields (light sources, lasers, biophotonics, detectors, optical components, atom and molecule confinement).
