Radio Science, 2025
This paper presents the design and optimization of a low‐cost, 5‐m radio telescope developed at Princess Nourah University (PNU), focusing on the 1,420 MHz spectral line of neutral hydrogen (HI) for studying the structure and dynamics of the Milky Way galaxy. The design process integrates key principles of radio telescope engineering, including the optimization of the parabolic dish's geometry, reflectivity, and feed horn design and positioning. Key design outcomes include achieving a sensitivity of and an angular resolution of 2.94° providing our telescope with the ability to detect faint cosmic signals. Additionally, the focal length was optimized at 1.75 m with conical feed horn of circular aperture radius of 81.7 mm providing a directivity of 6.47 dB and an aperture efficiency of 51% achieving semi‐optimal illumination for the designed reflector to minimize the signal loss. The resulting telescope gain of approximately 35 dB supports clear signal capture within the required frequency range. These performance metrics were verified through both simulations and experimental observations, confirming the high performance of our proposed radio telescope design. The advantages of this design include its affordability, replicability, and suitability for educational and research purposes, making it an accessible tool for radio astronomy studies in developing regions. The proposed radio telescope offers a cost‐effective solution for institutions seeking to engage in astronomical research and develop hands‐on learning experiences in antenna design and signal processing.

Field-Conformal Septa in Circular Waveguides
Walid M. Dyab, Mourad S. Ibrahim, Ahmed A. Sakr
IEEE Antennas and Propagation Society AP S International Symposium Digest, 2024
This paper introduces an innovative approach to waveguide polarizer design, utilizing field-conformal septa. The septa can be either dielectric or conducting, to enhance polarization control, and depending on the required application. The key enabler of this design approach is the advent of high-precision 3D printing technology, allowing for the accurate fabrication of complex, field-conformal shapes tailored to specific waveguide requirements. A detailed analysis based full-wave simulations is presented. This paper demonstrate the potential of field-conformal septa to significantly facilitate the design and improve the performance of waveguide polarizers.
Maximizing the Gap Height in Gap-Waveguides with Helical Wires Operating at the Vicinity of Resonance
Walid M. Dyab, Mourad S. Ibrahim, Ahmed A. Sakr, Ke Wu
IEEE Transactions on Microwave Theory and Techniques, 2023
Gap-waveguides made of bed-of-nails are revisited with special interest given to the maximum practically achievable gap height. In the cases where the gap height is to be maximized, it is important to have excitation techniques that are also conforming to the same gap height. To achieve this, various forms of gap-waveguides are investigated. The most suitable form is found to be the groove-gap-waveguide with top/bottom excitation. This type is called here separated-gap-waveguide (SGW). The maximum theoretical gap height between the top surface of the nails and the cover plate is a quarter wavelength. However, this is achieved at the expense of usable bandwidth. A practical experiment is presented to validate this feature. To increase this theoretical limit, the SGW made of bed-of-helical wires (springs) is investigated. In this case, the frequency bandgap is found to be in the vicinity of the first resonance of the helical wires. The benefits of using bed-of-springs instead of bed-of-nails are exposed in this article. The theoretical analysis needed to justify the use of the springs despite their difficult implementation is discussed. The benefits include minimizing the height of the bed structure itself while adding the saved height to the gap height. Furthermore, the use of bed-of-springs allows the frequency of operation to be much lower compared to the use of bed-of-nails. A comparison between the two structures is presented based on experimental results.
Lateral and Rotational Misalignment Tolerance in Separated Gap Waveguides made of Periodic Bed-of-Nails

17th European Conference on Antennas and Propagation Eucap 2023, 2023
Various forms of misalignment in separated gap waveguides made of periodic bed-of-nails are investigated numerically. Separated gap waveguides which are suitable for wireless power transfer applications are considered in this analysis. Two equivalent problems using perfect magnetic conductor boundaries are derived from the original problem with the periodic structure. The two equivalent problems are validated using simulation and prototype measurements. The equivalent problems are then solved with a parametric sweep to investigate the effect of lateral and rotational misalignment on this type of waveguides. The numerical results are plotted and compared to investigate the tolerance of gap waveguides in terms of power transfer efficiency.

Common-Strip Coupler Mode-Matched Interface for mmW and THz Chip-to-Chip Waveguides

2020 50th European Microwave Conference Eumc 2020, 2021
A mode-matched transition is proposed for millimeter wave and terahertz signal communication between integrated circuits and dielectric waveguide links. An on-chip transmission line is proposed to efficiently extract/deliver electromagnetic signals from/to chip-to-chip interconnects. The transition is based on two back-to-back microstrip transmission lines (on- and off-chip) sharing a common-strip. Thus, the proposed transition is called common-strip coupler (CSC) interface. The off-chip microstrip is constructed by a dielectric substrate that is flipped and stacked over the chip. The CSC couples the entire signal from the on-chip microstrip line to the off-chip line. The coupled signal could be entirely transmitted to a nonradiative dielectric waveguide link without the need for a matching section. This is due to mode matching; that is the field distribution of the dominant mode of an NRD waveguide is naturally matched to the quasi-TEM mode of the microstrip transmission line. The theoretical concept of the proposed transition at 300 GHz is explained and supported with design procedure and full-wave simulation results.
Ridge Gap Waveguide Enabled Wireless Power Transfer for Electric Vehicle Applications
Walid M. G. Dyab, Mourad S. Ibrahim, Ahmed A. Sakr, Ke Wu
2020 50th European Microwave Conference Eumc 2020, 2021
A technique for wireless power transfer based on a ridge gap waveguide structure is proposed. This technique is named as "Contact-Less Transmission-Line Wireless Power Transfer, CLTL-WPT". The idea is stemmed from the fact that the ridge gap waveguides are low loss transmission lines which consist of a base and a cover which are not in ohmic contact, thus allowing for an air gap in between. The theoretical efficiency of the proposed wireless power transfer is well compared to the conventional methods. The proposed technique is presented in the context of a high-power wireless charger for electric vehicle applications. An analytical design procedure of the ridge gap waveguide with respect to such an application is shown in details. The presentation is supported with full wave simulations. The main challenges and limitations are addressed.
