Summary
This study compared four Terahertz (THz) molecular absorption loss models for drone communications. Results show high consistency among models, with notable differences in vertical communication scenarios.
Area of Science:
- Wireless communication
- Atmospheric physics
- Electromagnetic wave propagation
Background:
- Terahertz (THz) frequencies are crucial for next-generation wireless systems, including drone communications.
- Accurate modeling of molecular absorption loss is essential for reliable THz system design.
- Existing models require comprehensive comparison for THz drone applications.
Purpose of the Study:
- To compare four widely used molecular absorption loss modeling tools for THz band drone communications.
- To evaluate model performance under various communication scenarios (horizontal and vertical) and atmospheric conditions.
- To assess the accuracy of a simple analytical model against established tools.
Main Methods:
- Comparison of International Telecommunication Union (ITU)-R P.676, Line-by-Line Radiative Transfer Model (LBLRTM), Atmospheric Model (am), and HITRAN on the Web (HotW).
- Simulation of path loss data using U.S. Standard 1976 and tropical atmospheric profiles.
- Analysis of horizontal and vertical communication links at different altitudes, frequencies, and distances.
- Validation of a simple analytical model by fitting data from ITU, LBLRTM, and am.
Main Results:
- High consistency was observed among the four molecular absorption loss modeling tools for THz band drone communications.
- Path loss prediction differences increased significantly in vertical communication scenarios compared to horizontal ones.
- The simple analytical model showed reasonable accuracy in predicting path loss based on data from the compared tools.
Conclusions:
- The study offers a comprehensive comparison of leading THz molecular absorption loss models for drone applications.
- Findings highlight the importance of considering communication geometry (horizontal vs. vertical) and atmospheric conditions for accurate path loss prediction.
- The validated analytical model provides a potentially simpler alternative for specific THz drone communication analyses.

Attenuated total reflectance (ATR) infrared spectroscopy is a powerful analytical technique used to study the composition of materials. It is widely employed in chemistry, materials science, forensic science, and other fields where sample characterization is required. ATR has several advantages over traditional transmission IR spectroscopy, including the requirement of little to no sample preparation and the ability to analyze a wide range of samples.

In electrical engineering, a lossless transmission line is characterized by a purely imaginary propagation constant and a resistive characteristic impedance. The ABCD parameters, which describe the relationship between the input and output voltages and currents, indicate an equivalent π circuit with an imaginary series impedance and a shunt admittance. This results in a transmission line that, when the product of the phase constant (beta) and the length of the line is less than pi,...

Consider a single-phase, two-wire, lossless transmission line terminated by an impedance at the receiving end and a source with Thevenin voltage and impedance at the sending end. The line, with length, has a surge impedance and wave velocity determined by the line's inductance and capacitance.
At the receiving end, the boundary condition states that the voltage equals the product of the receiving-end impedance and current. This relationship is expressed as a function of the incident and...

01:21IR Absorption Frequency: Hybridization

Hydrocarbons such as alkanes, alkenes, and alkynes show characteristic C–H stretching absorption bands. These IR stretching frequencies depend on the hybridization of the involved carbon atom and can be explained in terms of the s character of each hybridized atomic orbital.
Among the sp, sp2, and sp3 hybridized orbitals, sp orbitals have the maximum s character (50%). Consequently, the electrons are held more closely to the nucleus, resulting in stronger and shorter C–H bonds that...

The provided content explores the behavior of traveling waves on single-phase lossless transmission lines. It begins with a single-phase two-wire lossless transmission line of length Δx, characterized by a loop inductance LH/m and a line-to-line capacitance C F/m. These parameters result in a series inductance LΔx and a shunt capacitance CΔx.
