    "abstract": "When a (frequency-domain) boundary value problem involving a homogeneous\nlinear material is solved to assess the validity of the Post constraint, a\nconflict arises between the fundamental differential equations of\nelectromagnetism in the chosen material and a naive application of the usual\nboundary conditions. It is shown here that the conflict vanishes when the\nboundary conditions are properly derived from the fundamental equations, and\nthe validity of the Post constraint in modern macroscopic electromagnetism is\nthereby reaffirmed.",
