In this paper, we numerically and experimentally demonstrate the inverse polarization effect in 3D printed polarizers for the frequency range of 0.5 -2.7 THz. The polarizers consist of 0.3 mm printed strip lines of conductive polylactic acid (CPLA, Proto-Pasta) separated by a 0.3 mm air gap. We report the extinction ratio of five polarizers fabricated with different thicknesses between 1 mm and 5 mm. The experimental and numerical results show that the proposed structure acts as a broadband polarizer between the range of 0.3 THz to 2.7 THz, in which the inverse polarization effect is clearly seen for frequencies above 0.5 THz. In the inverse polarization effect, the transmission of the TE component exceeds that of the TM component, in contrast to the behavior of a typical wiregrid polarizer. Extinction ratios higher than 20 dB for the 5 mm device are reported within the inverse polarization region. This is the first report of the inverse polarization effect in 3D printed structures for the terahertz range.

“…Recently, additive manufacturing (or 3D printing) of EM designs and antennas has gained traction as a means of offering rapid prototyping of EM structures [10][11][12][13][14][15][16][17][18]. In [10], a microstrip patch antenna operating at 7.5 GHz was fabricated using a fused filament technique to print the dielectric part and an ultrasonic wire mesh embedding technique for the conductor part.…”

We demonstrate a 3D printed holographic metasurface antenna for beam-focusing applications at 10 GHz within the X-band frequency regime. The metasurface antenna is printed using a dual-material 3D printer leveraging a biodegradable conductive polymer material (Electrifi) to print the conductive parts and polylactic acid (PLA) to print the dielectric substrate. The entire metasurface antenna is 3D printed at once; no additional techniques, such as metal-plating and laser etching, are required. It is demonstrated that using the 3D printed conductive polymer metasurface, high-fidelity beam focusing can be achieved within the Fresnel region of the antenna. It is also shown that the material conductivity for 3D printing has a substantial effect on the radiation characteristics of the metasurface antenna.

“…However, this technique provides the lowest printing resolution and high surface roughness, as compared with the other techniques. The DLP [8,9] technique uses ultraviolet (UV) to create a pattern by selectively curing a resin-based photopolymer. The resolution of this technique depends on UV light spot size.…”

This paper presents a portable 3D-printed lens antenna fed by a standard rectangular waveguide at X-band for object classification. The proposed lens antenna can integrate with the standard rectangular waveguide without any additional assistant tools. A high impact polystyrene is used to design the 3D-printed hemispherical lens antenna by using the fused deposition modelling technique. This additive manufacturing gives several advantages including rapid prototyping, better cost and time effectiveness. Five lens radiuses, e.g., 20 mm, 30 mm, 40 mm, 50 mm, and 60 mm, are investigated to increase the gain of the antenna. The optimum dielectric tapered transition dimensions are simulated and obtained by using the 3D EM Simulation tool CST Studio, resulting in the reflection coefficient (S 11) of five lens antennas better than −10 dB across the WR-90 band. From the simulation results, the lens radiuses of 20 mm, 30 mm, 40 mm, 50 mm, and 60 mm, provide the average realized gain of 12.9 dBi, 15.2 dBi, 16.7 dBi, 17.7 dBi, and 18.6 dBi, respectively. To confirm the antenna performances of the proposed design, two lens radiuses, e.g., 20 mm and 30 mm are selected to fabricate. The gains of the lens radius of 20 mm and 30 mm are 12.1 dBi, and 14.2 dBi, respectively. The half-power beamwidth (HPBW) of lens radius of 20 mm and 30 mm are approximately 35 • and 24 • , respectively. The proposed dielectric lens antenna also offers other advantages, such as ease of design, low fabrication and material cost, and ease of mount and un-mount with WR-90 waveguide flange. Moreover, the narrow HPBW of lens antenna fed by standard waveguide can be applied to improve the resolution of the imaging system.
