Design of a seven-band perfect metamaterial absorber for THz sensing applications
Abstract This paper presents the design of a perfect metamaterial absorber tera-Hertz (THz) frequencies. The proposed absorber is developed using a square loop enclosing a highly convoluted swastika element. The arms of the swastika elements are coiled to create a square spiral configuration to incr...

| 520 | |a Abstract This paper presents the design of a perfect metamaterial absorber tera-Hertz (THz) frequencies. The proposed absorber is developed using a square loop enclosing a highly convoluted swastika element. The arms of the swastika elements are coiled to create a square spiral configuration to increase the electrical length of the resonator without increasing the size of the unit cell absorber. The proposed unit cell has multiabsorption characteristics with absorption peaks at 0.82, 1, 1.24, 1.54, 1.85, 2.2 and 2.5 THz. The corresponding absorptivity is greater than 80% in all the reported frequencies. The electrical size of the proposed absorber is 0.$ 42λ_{eff} $ × 0.$ 42λ_{eff} $, where $ λ_{eff} $ is the effective wavelength calculated at 0.82 THz. The proposed absorber has structural symmetry and has identical absorption spectra for both TE and TM modes of operation. The angular stability is investigated, and the performance is stable for the angles of incidence up to 70°. The proposed absorber has a small frequency ratio and can be used for THz material sensing. The prototype absorber as a sensor is simulated, and the results are presented. | ||

The proposed absorber is developed using a square loop enclosing a highly convoluted swastika element. The arms of the swastika elements are coiled to create a square spiral configuration to increase the electrical length of the resonator without increasing the size of the unit cell absorber. The proposed unit cell has multiabsorption characteristics with absorption peaks at 0.82, 1, 1.24, 1.54, 1.85, 2.2 and 2.5 THz. The corresponding absorptivity is greater than 80% in all the reported frequencies. The electrical size of the proposed absorber is 0.$ 42λ_{eff} $ × 0.$ 42λ_{eff} $, where $ λ_{eff} $ is the effective wavelength calculated at 0.82 THz. The proposed absorber has structural symmetry and has identical absorption spectra for both TE and TM modes of operation. The angular stability is investigated, and the performance is stable for the angles of incidence up to 70°. The proposed absorber has a small frequency ratio and can be used for THz material sensing. The prototype absorber as a sensor is simulated, and the results are presented.

The proposed absorber is developed using a square loop enclosing a highly convoluted swastika element. The arms of the swastika elements are coiled to create a square spiral configuration to increase the electrical length of the resonator without increasing the size of the unit cell absorber. The proposed unit cell has multiabsorption characteristics with absorption peaks at 0.82, 1, 1.24, 1.54, 1.85, 2.2 and 2.5 THz. The corresponding absorptivity is greater than 80% in all the reported frequencies. The electrical size of the proposed absorber is 0.$ 42λ_{eff} $ × 0.$ 42λ_{eff} $, where $ λ_{eff} $ is the effective wavelength calculated at 0.82 THz. The proposed absorber has structural symmetry and has identical absorption spectra for both TE and TM modes of operation. The angular stability is investigated, and the performance is stable for the angles of incidence up to 70°. The proposed absorber has a small frequency ratio and can be used for THz material sensing. The prototype absorber as a sensor is simulated, and the results are presented.</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">THz absorbers</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">perfect metamaterial absorber</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">THz sensors and THz detectors</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="773" ind1="0" ind2="8"><subfield code="i">Enthalten in</subfield><subfield code="t">Pramāna</subfield><subfield code="d">Bangalore : Indian Inst. of Science, 1973</subfield><subfield code="g">96(2022), 4 vom: 15.

Design of a seven-band perfect metamaterial absorber for THz sensing applications |
| abstract |
Abstract This paper presents the design of a perfect metamaterial absorber tera-Hertz (THz) frequencies. The proposed absorber is developed using a square loop enclosing a highly convoluted swastika element. The arms of the swastika elements are coiled to create a square spiral configuration to increase the electrical length of the resonator without increasing the size of the unit cell absorber. The proposed unit cell has multiabsorption characteristics with absorption peaks at 0.82, 1, 1.24, 1.54, 1.85, 2.2 and 2.5 THz. The corresponding absorptivity is greater than 80% in all the reported frequencies. The electrical size of the proposed absorber is 0.$ 42λ_{eff} $ × 0.$ 42λ_{eff} $, where $ λ_{eff} $ is the effective wavelength calculated at 0.82 THz. The proposed absorber has structural symmetry and has identical absorption spectra for both TE and TM modes of operation. The angular stability is investigated, and the performance is stable for the angles of incidence up to 70°. The proposed absorber has a small frequency ratio and can be used for THz material sensing. The prototype absorber as a sensor is simulated, and the results are presented. © Indian Academy of Sciences 2022 |
