To the Editor:We were interested in the article,which reported a woman with calcinosis,Raynaud’s phenomenon,esophageal dysmotility,sclerodactyly and telangiectasia(CREST)syndrome who developed progressive dyspnea on exertion and was later diagnosed with pulmonary capillary hemangiomatosis(PCH)that was confirmed by an open lung biopsy.[1]We would like to remark that the diagnosis of PCH is inconclusive from just history,treatment,and histological *** case also does not specify a clear connection between PCH and CREST syndrome;therefore,we believe we need to explore another possible disease association.

Broadband and perfect terahertz absorber based on multilayer metamaterial using cross-ring patterned structures is proposed and investigated. The structure of the absorber is double absorption layers consisting of a chromium cross ring and eight isosceles right triangles. The unique structure of the double absorbing layers excites the electric dipole multimode resonance, giving rise to high absorption performance. Meanwhile, the influence of construal parameters on absorber behavior is also discussed. The numerical results show that the absorption achieves over 90% ranging from 2.45 THz to 6.25 THz and 99% absorption in the range of 3.7—5.3 THz. The realization of broadband and perfect absorber is described using the impedance matching principle. It is obviously found that the absorber is insensitive to the high angle of incidence for both transverse electric(TE) and transverse magnetic(TM) polarizations. Compared with the former reports, this absorber has remarkable improved absorption efficiency and smaller period. The terahertz absorber may be found applications in the fields of energy capture and thermal detection.
