A type of telecommunication technology called an ultra-wideband (UWB) is used to provide a typical solution for short-range wireless communication due large bandwidth and low power consumption in transmission reception. Printed monopole antennas are considered as preferred platform implementing this because its alluring characteristics such light weight, cost, ease fabrication, integration capability with other systems, etc. Therefore, compact-sized printed antenna improved gain efficiency...
We introduce laser interference lithography (LIL) as a tool to fabricate hierarchical photonic nanostructures inspired by blue Morpho butterflies. For that, we utilize the pattern in vertical direction addition conventional horizontal one. The creates lamellae exploiting back reflection from substrate. patterns ridges of Christmas tree like structure. artificial replica produced with this technique feature brilliant iridescence up an incident angle 40°.
Grating based X-ray differential phase contrast imaging (DPCI) allows for high of materials with similar absorption characteristics. In the last years' publications, small animals or parts human body like breast, hand, joints blood vessels have been studied. Larger object s could not be investigated due to restricted field view limited by available grating area. this paper, we report on a new stitching method increase area significantly: individual gratings are merged carrier substrate....
Grating based X-ray phase contrast imaging is on the verge of being applied in clinical settings. To achieve this goal, compact setups with high sensitivity and dose efficiency are necessary. Both can be increased by eliminating unwanted absorption beam path, which mainly due to grating substrates. Fabrication gratings via deep lithography address issue replacing commonly used silicon substrate materials lower that fulfill certain boundary conditions. Gratings were produced both graphite...
The famous non-iridescent blue of the Morpho butter by is caused a `Christmas tree' like nanostructure which challenge for common fabrication techniques. Here, we introduce method to fabricate this complex morphology utilizing dual beam interference lithography. We add reflective coating below photoresist create second pattern in vertical direction exploiting back reflection from substrate. This exposes lamella structure into photosensitive polymer while horizontal determines distance...
Point focus x-ray mosaic lenses are limited in aperture by the aspect ratio that can be reached micro fabrication process. In lithography based processes, which used to fabricate lens pillar structures, achievable is restricted structure collapse due capillary forces occur during drying after development. Capillary avoided freeze drying, hence avoiding direct phase change from liquid gas. Substituting conventional using cyclohexane at a temperature of −10 °C, we could increase for triangular...
Background: Deep x-ray lithography using synchrotron radiation is a prominent technique in the fabrication of high aspect ratio microstructures. The minimum lateral dimensions producible are limited by primary dose distribution and secondary effects (Fresnel diffraction, electrons scattering, etc.) during exposure. Aim: influence on microstructures with submicrometer dimension deep characterized. Approach: under investigation one-dimensional gratings. structural simulated compared to...
In this paper, a millimeter-wave quad-band dielectric resonator antenna (QD-DRA) for fifth-generation (5G) applications, is suggested gain enhancement. The DRA designed in conjunction with superstrate, placed over substrate material of RT/Duroid 5880, which characterized by relative permittivity equal to 2.2, tangent loss 0.0009, and compact size an overall dimension 12 mm × 11 0.25 mm. This achieved the quad bands wireless communication, i.e., it resonates at four different frequencies 28...
Lidar has brought the much-needed revolution in autonomous car driving technology. Combination of ABS (antilock braking system), Sensors and a novel pneumatic bumper makes system vehicles much safer intelligent. Within this paper, we intend to provide an introductory overview technology, which will make during high speed or crash. Finally, methods for coordination between sensors, were analyzed.
