Abstract

This academic recognition profile presents the research record of Qifa Liu, affiliated with Nanjing University of Posts and Telecommunications. The supplied Scopus information identifies photonic crystal as the relevant subject area and records one indexed document, 57 citations, and an h-index of 1.[1] Photonic crystals are engineered structures in which periodic variations in refractive index can influence the propagation of electromagnetic waves. Their properties have been investigated for applications involving optical filtering, waveguiding, sensing, communications, and other photonic technologies.[2][3]

Introduction

Photonic crystals are periodic dielectric or electromagnetic structures designed to control the propagation of light. The periodic arrangement of materials with different refractive indices can produce photonic band structures and, under appropriate conditions, frequency ranges in which particular electromagnetic modes are restricted or modified.[2] These properties have made photonic crystals an important area of research within modern optics, photonics, materials science, and optical engineering.

Research on photonic crystals encompasses theoretical modelling, numerical analysis, fabrication, characterization, and device-oriented applications. Depending on structural geometry and material composition, photonic crystal systems can be investigated for waveguiding, optical filtering, resonant phenomena, sensing, and integrated photonic components.[3][4]

Research Profile

The supplied research profile associates Qifa Liu with Nanjing University of Posts and Telecommunications and identifies photonic crystal as the principal subject area. The bibliometric record supplied for this profile contains one Scopus-indexed document and 57 citations, with an h-index of 1.[1] Because bibliometric indicators can change as databases are updated and additional publications become indexed, the values presented here should be understood as profile-specific measurements rather than permanent characteristics.

Research Contributions

Photonic crystal research contributes to the broader development of technologies capable of manipulating electromagnetic waves through engineered material structures. Periodic optical architectures can be designed to modify dispersion, confinement, transmission, and resonant behaviour, providing a platform for studying fundamental optical phenomena as well as potential device applications.[2]

The supplied subject classification places Qifa Liu’s research within this wider photonic crystal field. On the basis of the information provided, the appropriate description is therefore focused on the researcher’s documented subject area rather than on attributing specific technical findings that are not included in the supplied record.

Publications

The supplied Scopus profile records one indexed document for Qifa Liu.[1] The available information does not provide the title, journal, publication year, authorship position, or complete bibliographic metadata for that document. Accordingly, this profile does not infer publication-specific claims beyond the bibliometric information supplied.

Research Impact

The supplied citation count of 57 indicates that the indexed work associated with the profile has received citations within the literature represented by the supplied Scopus record.[1] The h-index of 1 indicates that at least one indexed publication has received at least one citation under the corresponding bibliometric calculation. Citation indicators are useful for describing scholarly visibility, but they do not independently measure methodological quality, originality, societal relevance, or the practical significance of individual research findings.

Within photonics, the broader scientific importance of photonic crystal research derives from its potential to control electromagnetic propagation at engineered length scales. Foundational studies have established the relevance of photonic band structures and defect-based optical confinement to the development of photonic devices and systems.[2][4]

Award Suitability

The supplied academic record provides a basis for considering Qifa Liu for an Innovative Research Award within the context of the Applied Scientist Awards. Relevant documented factors include an identified research specialization in photonic crystal, affiliation with Nanjing University of Posts and Telecommunications, and measurable citation activity associated with the supplied Scopus profile.[1]

Award suitability should nevertheless be determined through the formal evaluation procedures established by the Applied Scientist Awards. Bibliometric information can support an assessment of research activity and visibility, while a complete award evaluation may also consider originality, technical contribution, research significance, publication quality, collaboration, and broader scientific or practical relevance.

Conclusion

Qifa Liu’s supplied academic profile identifies a research focus in photonic crystal and an affiliation with Nanjing University of Posts and Telecommunications in China. The corresponding Scopus information records one document, 57 citations, and an h-index of 1.[1] These indicators provide a concise quantitative representation of the researcher’s indexed scholarly activity and citation visibility. Further evaluation of research quality and innovation would require examination of the underlying publications and their scientific contributions.
