چکیده
Few examples of individual polymer-based 3-D printed quasi-optical component types have been previously demonstrated above ca. 100 GHz. This paper presents the characterization components and complete subsystems for applications operating at G-band (140 to 220 GHz). Two low-cost consumer-level printing technologies (vat polymerization fused deposition modeling) are employed, normally associated with microwave frequencies longer wavelength applications. Here, five different investigated; rectangular horn antennas, 90° off-axis parabolic mirrors, radiation absorbent material (RAM), grid polarizers dielectric lenses. As an alternative conventional electroplating, gold-leaf gilding is used polarizer. A detailed investigation undertaken compare performance our mirrors RAM their commercial equivalents. In addition, a fully printed, RAM-lined housing central two-axis rotational platform constructed performing two-port measurements horn-mirror-polarizer-mirror-horn subsystem. Measured results generally show excellent performances, although polarizer limited by minimum strip width, separation distance metallization thickness. The ultra-low cost, `plug play' designed give fast measurement setup, while minimizing misaligning losses. Its lining suppress reflections due diffraction from under test that may cause adverse multi-path interference. Our work investigates each type integrates them within subsystem assemblies; well those technologies. opens-up new opportunities rapid prototyping front-end upper-millimeter-wave subsystems.

The rising prevalence of high throughput screening and the general inability of (1) two dimensional (2D) cell culture and (2) release studies to predict in vitro in neurobiological and pharmacokinetic responses in humans has led to vivo greater interest in more realistic three dimensional (3D) benchtop platforms. Advantages of 3D human cell culture over its 2D analogue, or even animal models,...
متن کامل140-220 GHz Imaging Front-end Based on 250 nm InP/InGaAs/InP DHBT Process
This paper presents a pre-amplified detector receiver based on a 250 nm InP/InGaAs/InP double heterojunction bipolar transistor (DHBT) process available from the Teledyne scientific. The front end consists of a double slot antenna followed by a five stage low noise amplifier and a detector, all integrated onto the same circuit. Results of measured responsivity and noise are presented. The recei...
متن کاملIntegrated Micromachined Waveguide Absorbers at 220 – 325 GHz
This paper presents the characterization of integrated micromachined waveguide absorbers in the frequency band of 220 to 325 GHz. Tapered absorber wedges were cut out of four different commercially available semi-rigid absorber materials and inserted in a backshorted micromachined waveguide cavity for characterization. The absorption properties of these materials are only specified at 10 GHz, a...
متن کاملLow cost optical interconnects [6478-3]
Optical interconnects to couple light from single mode fiber to waveguides and photonic elements have remained expensive due to tight alignment tolerances, materials choices, fabrication methods and assembly processing techniques. Methods that have been used to lower the cost of optical interconnects will be reviewed and compared to current and future market application demands. Design approach...
