Triple

Given a phrase, classify it is english named entity (e.g., persons, organizations, works of art) in Latin script, or not (e.g., literals, dates, URLs, verbose phrases). For disambiguation, the statement where the phrase occurs as object is also given. Please return a JSON object with `phrase` (string, the phrase being analyzed) and `is_ne` (boolean, indicating whether the phrase is a Named Entity).

Phrase: Kirchhoff integral theorem | Statement: [Kirchhoff diffraction theory, usesConcept, Kirchhoff integral theorem]

Target entity: Kirchhoff integral theorem
Context triple: [Kirchhoff diffraction theory, usesConcept, Kirchhoff integral theorem]

• A. Kirchhoff diffraction theory
  Kirchhoff diffraction theory is a classical wave optics framework that models light propagation and diffraction by treating wavefronts as superpositions of secondary spherical waves emitted from an aperture.
• B. Etherington reciprocity theorem
  The Etherington reciprocity theorem is a fundamental result in relativistic cosmology that links luminosity distance and angular diameter distance, underpinning observational tests of the expanding universe.
• C. Huygens–Fresnel principle
  The Huygens–Fresnel principle is a fundamental concept in wave optics that explains how every point on a wavefront acts as a source of secondary wavelets whose interference determines the wave’s subsequent propagation and diffraction.
• D. Fresnel diffraction theory
  Fresnel diffraction theory is a wave-optics framework that describes how light diffracts when source or observation distances are finite, using near-field approximations derived from the Huygens–Fresnel principle.
• E. Fresnel integrals
  Fresnel integrals are special functions in mathematics that describe the complex oscillatory behavior of wave diffraction and interference, particularly in optics.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.

Entity: Kirchhoff integral theorem
Triple: [Kirchhoff diffraction theory, usesConcept, Kirchhoff integral theorem]

The Kirchhoff integral theorem is a fundamental result in wave theory that expresses the value of a wave field inside a region in terms of its values and normal derivatives on the region’s boundary, forming the basis for many diffraction and propagation analyses.
