“…Besides, contactless measurement setups require costly components such as parabolic mirrors, reflectors, and alignment units. THz microstructured fibers can also be an essential structure for designing functional devices, such as THz Bragg fiber filtering antennas, THz gas/liquid sensors [22], and THz endoscopy front-ends.…”

In this paper, a novel and innovative approach to characterize THz Bragg fibers using a horn-type adapter is presented, enabling a two-tier calibration method for a direct, efficient, and reliable way to measure THz Bragg fibers, including return loss and insertion loss. The proposed approach is robust, accurate, and repeatable, making it suitable for designing and optimizing THz Bragg fibers and systems and enabling continued research and development. The present study employs a calibration approach, utilizing Short-Short-Load-Thru (SSLT) and Thru-Reflect-Line (TRL) calibrations. The horn-type adapter connects a standard WR-3.4 rectangular waveguide and a THz Bragg fiber, allowing the mode conversion from the TE10 mode in the rectangular waveguide to the HE11 mode in the Bragg fiber, with a middle stage of the TE11 mode in the tapered horn region. Additionally, the highly accurate measurement quality presented advantages compared to the existing THz measurement setups, for example, setup complexity, coupling efficiency, impedance adjustability, and less sensitivity to measurement environments, etc. The present approach shows advantages in experimental setup complexity, coupling efficiency, impedance adjustability, measurement repeatability, operator experience required, and setup tool cost compared to other existing THz measurement techniques.

“…The equipment used in this research was designed by choosing LoRa model from the producer which is Semtech No. SX1276 having working frequency area at 920-925MHz and the highest transmission power at +14dBm [10] [11] connected to microcontroller processing unit, an 8-bit sized Arduino nano in reading the data value gained from the sensor metering the heat temperature from wild fire. However, from testing result, it showed the use of setting the signal transmission value of LoRa at different values such as modulating bandwidth of sending data will result in network coverage and data propagation delay.…”

This study proposes the LoRa-Based Mesh Sensor Network without relying on LoRaWAN connection sending the communication data in the form of Star-to-Star, it can be sends the data in the form of peer-to-peer without the gateway. In the case that a longer distance is needed, the system is connected by a means of multi-hop presenting the hardware and software model through the use of low voltage power. Then, the testing is done using point to point and the received signal is measured by a gauge and compared with the model in accordance with the theoretical principle.
