Investigation of electromagnetic response of terahertz metamaterial by using split-disk resonator

New Metamaterial Absorber Based on Electromagnetic Coupling of Triangular SRR and Square SRRs for X-Band RADAR Applications

“…Geometrically, the resonator SRR is formed by two outer and inner split rings with two opposing interrupts to have the capacitive effect. Physically, the resonator SRR can support too small wavelengths; see lengths of the order of a few microns [16].…”

Reconfigurable metamaterials for optoelectronic applications

“…[85] In the Lin's research group, they proposed a series of THz metamaterial sensors and switches, such as three designs of tunable multi-resonance of THz metamaterials composed of single-, dual-, and triple-split-disk resonators (Figure 6(h)), [95] a tunable THz metamaterial with single-band and Figure 6. Reconfigurable metamaterials in THz spectrum range for (a and b) absorbers, [90,91] (c and d) polarizers, [75,92] (e and f) filters, [93,94] (g and h) sensors, [85,95] and (i-l) switches [96][97][98][99] applications.…”

“…dual-band filtering and switching characteristics ( Figure 6(i)), [96] a multifunctional split-disk resonator THz metamaterial ( Figure 6(j)), [97] a three-dimensional double split-ring resonators with high tuning range ( Figure 6(k)) [98] and three-coaxial-complementary-SRR metamaterial with single-/dual-band switching tunability ( Figure 6(l)). [99] The fruitful results provide the reconfigurable THz metamaterials to possess multifunctional characteristics.…”

Switching of plasmonic resonances in multi-gap resonators at terahertz frequencies

“…They have been widely applied to control the radiations in the optical, infrared, terahertz and microwave ranges [2][3][4][5][6][7][8][9][10][11]. In the terahertz band, extensive studies on functional metamaterial devices have been well demonstrated, including invisibility cloaks, sensors, lenses, filters, modulators, etc [12][13][14][15][16][17][18][19][20][21][22][23][24][25]. In a general way, the essential rule for designing metamaterials is to build up certain resonance modes in the unit cell, such as inductor-capacitor circuit (LC) resonance, Fano resonance, dipolar resonance, and so forth.…”
