In this study, electromagnetic (EM) energy harvesting by using metamaterial absorber is numerically explained. Operation frequency is 2.40 GHz since it is the industrical scientific and medical (ISM) band. This band is especially chosen due to most of the customer electronic devices are working in this band. Split ring resonator that have two splits on it used in this study, chip resistors are placed on these splits for wireless energy transfer to the devices. 83.6% efficient electromagnetic energy harvesting is theoretically realized.


Metamaterial-based energy harvesting for GSM and satellite communication frequency bands
A metamaterial-based energy harvesting structure has been designed and experimentally tested in this study. The proposed structure has square and split ring resonators placed in different angles on the back and front sides for compatible multiband operation in energy harvesting. Resonance points have been defined at 900 MHz, 1.37 GHz, 1.61 GHz, 1.80 GHz, and 2.55 GHz, by simulation and experimental methods. These points correspond to Global System for Communication (GSM) 900, GSM 1800, Universal Mobile Tele...
Perfect metamaterial absorber-based energy harvesting and sensor applications in the industrial, scientific, and medical band
Bakir, Mehmet; KARAASLAN, MUHARREM; Dincer, Furkan; DELİHACIOĞLU, KEMAL; Sabah, Cumali (2015-09-01)
An electromagnetic (EM) energy harvesting application based on metamaterials is introduced. This application is operating at the the industrial, scientific, and medical band (2.40 GHz), which is especially chosen because of its wide usage area. A square ring resonator (SRR) which has two gaps and two resistors across the gaps on it is used. Chip resistors are used to deliver the power to any active component that requires power. Transmission and reflection characteristics of the metamaterial absorber for en...

Gunduz, Ozan T.; Sabah, Cumali (2015-09-09)
We propose and examine an enhanced version of a multi-band metamaterial absorber for an energy harvesting application. The numerical results of the multi-band absorption characteristics of no-load conditions are presented and compared with the loading conditions. At most % 50 of the incoming wave energy whose correspondence is 0.25 Watt is converted to real power at the resistive loads at 5.88 GHz by the usage of 2000 ohms loads. In order to evaluate the harvesting efficiency, three different types of effic...
Dual-band high-frequency metamaterial absorber based on patch resonator for solar cell applications and its enhancement with graphene layers
Ustunsoy, Mehmet Pasa; Sabah, Cumali (2016-12-05)
In this paper, a dual-band high-frequency metamaterial absorber based on patch resonator is designed and analyzed for solar cells. In order to obtain a metamaterial absorber, metal-semiconductor-metal layers are combined. The results of the designed structure are shown in the infrared and visible ranges of solar spectrum. Structural parameters and dimensions of the device have a significant importance on the performance of the designed absorber. The simulations are carried out with full-wave electromagnetic...
Wide Bandwidth Absorption in the MWIR Region using a Thin and Simple Metamaterial Absorber
ÜSTÜN, KADİR; Sayan, Gönül (2017-09-27)
In this study, metamaterial absorber structures that operate in the mid-wave infrared (MWIR) region are presented. The advantage of the design stems from the high absorptance in the region of interest and the ease of fabrication. Fabrication stage is facilitated by large in-plane geometric dimensions of the metamaterial pattern and small thickness of the full absorber geometry.
