“…These holes were similar to an array of dielectric circular waveguides having a length that was five times the diameter of the waveguide. Both perforated absorbers had a thickness of 15 mm, which was less than the previously-designed pyramid absorber [3,25]. Figure 9 shows the two perforated, ricehusk microwave absorbers with circular holes.…”

“…At low frequencies there are wider-angle reflections, but, due to the availability of moredirectional antennas at higher frequencies, the levels of the wide-angle reflections can be controlled [23]. To improve the performance of the absorber, different materials can be used, such as using added tire dust [24], split-ring resonators (SRR) [25][26][27], electronic band gaps (EBG) [28], and photonic band-gap (PBG) structures [29]. Non-perforated and perforated designs were investigated in this study.…”

Abstract-Biomass used for energy, whether it is extracted from forest residues or agricultural waste, contributes in many areas, such as power production, the construction industry, and also as a major source of different organic and inorganic compounds in the petrochemical industry. In recent years, research has identified a very remarkable use of agricultural waste, especially rice husks, as a microwave absorber in a pyramidal shape. However, absorbers built in this shape are fragile and require a very high degree of care, especially near the access panels, doors, and high traffic areas of the anechoic facility. This paper presents the results of a detailed experimental investigation of a more-robust, new design that is based on the concept of impedance or dielectric grading of rice-husk material. The absorber was fabricated using multiple layers of rice-husk material with increasing dielectric loss along the incident wave propagation axis. This type of fabrication technique provides more robust design of the microwave, rice-husk absorber with less thickness, as compared to the geometricallytapered, pyramid, or wedge absorbers. Free-space transmission and radar cross section (RCS) methods have been used, to study the electromagnetic compatibility (EMC) performance over the frequency range of 4-8 GHz. After the receiving equipment was calibrated by the thru-reflect-line (TRL) calibration technique, the experiments were performed inside the anechoic chamber. The performance of the absorber was evaluated by incorporating the effects of circular-hole perforation, cross-polarized seams, and different metallic back plates. The proposed absorber demonstrated good performance (< −10 dB) for normal and 60 • off the normal incident angles over the frequency range of 4-8 GHz. Reflectivity performance also was found to be comparable to one of the commercially-available absorbers.

“…The next stage is the measurement of reflection loss using the radar cross section (RCS) method [38][39][40][41]. The equipment used in this measurement was a signal generator, a spectrum analyzer, a pair of coaxial cables, seven pairs of horn antennas, the reference metal and a tripod to hold the horn antennas and the reference metal [42,43].…”

Abstract-The need to find ways to effectively utilize the large quantities of agricultural waste that are produced is indicative of the huge potential associated with producing an alternative pyramidal microwave absorber for anechoic chamber-testing applications. We propose the development of a pyramidal microwave absorber that can use sugar cane bagasse (SCB), a byproduct from the production and processing of sugar cane, as the absorbent. In this paper, we report the results of our use of dielectric probe measurement to determine the dielectric constant and loss tangent of SCB. These values were used to model and simulate an SCB pyramidal microwave absorber in Computer Simulation Technology's (CST's) Microwave Studio. This absorber was operated in the microwave frequency range between 0.1 GHz and 20.0 GHz.

“…This small particle may be made to resonate at a frequency determined by the capacitance and inductance of the ring structure. Many applications have been reported with SRR, such as UWB antenna [12], AMC structure [13,14] and filter [15,16]. Miniaturization of patch antenna with SRR is proposed by Raoul O. Ouedraogo [17].…”

Abstract-A new design methodology for multi-band rectangular microstrip antenna using a metamaterial-inspired technique is proposed. The methodology uses the metal disk with SRR-shaped slot placed horizontally between the patch and the ground plane. With the introduction of the split ring, sub-wavelength resonance can be achieved while the dominant mode of patch cavity remains the same, so the antenna can operate at multi resonant frequencies. Construction of the multi-band antenna requires only the sandwiching of two etched circuit boards. The antenna has the properties of low profile, easy fabrication and low cost. Dual-band and tri-band antennas are fabricated and measured, which validate the design methodology.
