Zusammenfassung:The TM shielding effectiveness (SE) analyses of slotted carbon fiber reinforced polymer (CFRP)-based shells are presented in this letter. The multifilament doublet current method (MFDCM) is deployed to simulate the scattered and penetrated fields in the considered situation. The inner and outer regions of a slotted shell are separated by a hybrid boundary, which contains the material and slot parts. The material part is constituted of multilayered CFRP materials, whereas the slot part is a virtual boundary. A tensorial boundary condition (TBC) is then constructed to stand for the slotted shell with a chain matrix. The MFDCM is subsequently formulated by employing the TBC to estimate the EM performances of interests. Different slot angles of the shell and conductivity of the CFRP material are considered in our numerical calculations. Only transverse magnetic (TM) case is considered herein, yet the transverse electric (TE) situation can be handled straightforwardly with a similar formulation.
