摘要： PROBLEM TO BE SOLVED: To make an electromagnetic wave absorbing area to be wide. SOLUTION: In an electromagnetic wave absorbing panel 3, three insulating substrates are arranged in parallel by leaving spaces. A matching film which absorbs a part of an arriving electromagnetic wave, makes the other part reflect and makes the remainder pass through, a division conductive film 22 and a reflection film reflecting the arriving electromagnetic wave are formed on the respective substrates in order from the arriving direction of the electromagnetic wave. A plurality of conductive patterns 24 which have shapes where change patterns whose width (b) changes like bmax→bmin→bmax are repeated at a prescribed period and which have film thickness (a) are disposed by leaving gaps 26 along the width direction. The width (d) of the gap 26 changes like dmin→dmax→dmin. The change ranges bmin to bmax of width (b) and the change ranges dmin to dmax of width (d) are decided in accordance with the frequency bands f1 to f22 of the electromagnetic wave to be absorbed. The electromagnetic wave arrived at the electromagnetic wave absorbing panel is absorbed at a high absorbing rate for the whole frequency bands f1 to f2.

摘要： PROBLEM TO BE SOLVED: To make an electromagnetic-wave absorber thin without lowering its electromagnetic-wave absorption performance. SOLUTION: A matching film 16 which absorbs a part of arrival electromagnetic waves and which reflects the remaining part is formed on one board from among boards 12 14 arranged in parallel, and a reflecting film 18 which reflects the arrival electromagnetic waves is formed on the other board, A split electric conductor 20 provided with many insulating boards 22 which are flat and longer and in which conductive films 24 are formed on the whole face on one side is installed between the matching film 16 and the reflecting film 18. The boards 22 are arranged in such a way that ends of the conductive films 24 formed on the adjacent hoards 22 are faced over a prescribed length apparently larger than the film thickness (a) of the conductive films 24 by keeping gaps (the boards 22). When the electromagnetic waves arrive, an electric charge is stored in the opposite parts of the conductive films 24, a stored electric charge amount is increased further by the Coulomb force generated by the electric charge, and the effective relative permittivity between the matching film 16 and the reflecting film 18 is increased.

摘要： PROBLEM TO BE SOLVED: To provide a method for absorbing electromagnetic wave by which an electromagnetic wave to be absorbed is absorbed by superposing an opposite-phase electromagnetic wave upon the electromagnetic wave and to provide a wave absorber which can absorb a wide band of electromagnetic waves by applying the method. SOLUTION: Between a resistance film which reflects part of arriving electromagnetic waves and transmits the other part of the waves and a reflecting film which reflects the arriving waves, an specific band reflecting antenna film on one surface of which many linear antenna elements having the same shape are formed at a fixed density and which only reflects a specific band of electromagnetic waves is provided. A specific band of electromagnetic waves arriving at an electromagnetic wave absorbing panel and having a frequency f1 are absorbed, because an electromagnetic wave Er11 reflected by the resistance film and another electromagnetic wave Er21 reflected by the reflecting antenna film become opposite in phase. In addition, another specific band of electromagnetic waves arriving at the absorbing panel and having a frequency f2 are absorbed, because an electromagnetic wave Er12 reflected by the resistance film and another electromagnetic wave Er22 reflected by the reflecting film become opposite in phase.

Related to the magnetic body plate of the magnetic body layer 32A, its major side is parallel to a first direction (the direction vertical to a paper face in figure (A)) orthogonal to the aligned direction while arrayed with a space in a second direction (the direction vertical to the paper face in figure (B)) orthogonal to the first direction. Related to the magnetic body plate of the magnetic body layer 32B, its major side is parallel to the second direction while arrayed with a space in the first direction.

摘要： PROBLEM TO BE SOLVED: To provide a wave absorptive panel which has incombustibility, a light weight, uniform layers between a conductive film for matching and divided conductive films and between the divided conductive films and a conductive film for reflection, and a wave absorbing characteristic that does not change much even when the incident angle of electric waves changes and does not become bulky. SOLUTION: The wave absorptive panel is constituted of a first insulating substrate 1 having the conductive film 2 for matching, a substrate 3 having the conductive film 4 for reflection which is faced oppositely to the substrate 1, and a second insulating substrate 5 which is faced oppositely to the substrates 1 and 3 between the substrates 1 and 3 and has the divided conductive films 6 on one surface. The first and second insulating substrates 1 and 5 are coupled with each other by interposing a first adhesive layer 7 which brings the substrates 1 and 5 nearer to each other while the layer 7 insulates the substrates 1 and 5 from each other between the substrates 1 and 5. In addition, the second insulating substrate 5 and substrate 3 are coupled with each other by interposing a second adhesive layer 8 which brings the substrates 5 and 3 nearer to each other to a prescribed distance or shorter between the substrates 5 and 3. This wave absorptive panel is used with the first insulating substrate 1 on the radio wave arriving side.

摘要： PROBLEM TO BE SOLVED: To widen an electromagnetic wave absorbance band and to make an electromagnetic wave absorbing body thinner. SOLUTION: A specific band reflective antenna film where many linear antenna elements of the same shape are formed with a constant density on the same plane for reflecting only an electromagnetic wave in a specific band is provided between a resistance film where a part of incoming electromagnetic wave is reflected while another part transmits and a reflective film which reflects the in-coming electromagnetic wave. A split conductor layer is provided between the resistance film and an antenna layer while a magnetic body layer is provided between the antenna layer and the reflective film. The electromagnetic wave of a frequency f1, in the specific band, which arrives at an electromagnetic wave absorbing panel is absorbed as the phase of an electromagnetic wave Er11 reflected on the resistance film is opposite to that of an electromagnetic wave Er21 reflected on the specific band reflective antenna film. The electromagnetic wave of frequency f2, in a prescribed band different from the specific band, which arrives at the electromagnetic wave absorbing panel is absorbed as the phase of the electromagnetic wave Er12 reflected on the resistance film is opposite to that of an electromagnetic wave Er22 reflected on the reflective film.
