Finite bandwidth (material conductivity properties) and surface roughness significantly decrease measured Casimir forces compared to idealized parallel plate models.
The claim addresses specific physical factors (finite bandwidth/conductivity and surface roughness) that alter the Casimir force relative to ideal models. Papers [0] and [2] explicitly confirm that real-world surface roughness and material properties (such as finite conductivity/bandwidth) reduce or suppress the Casimir force compared to idealized calculations. The remaining papers are tangential and do not discuss Casimir force corrections.
