Asymptotic wave-like modeling of dielectric lenses
(IEEE, 2007)We propose asymptotic wave-like approximations for the accurate modeling of dielectric lenses used in quasi-optical systems of millimeter, submillimeter, and infrared wave applications. For the comparison, we obtain an ... -
Bow tie shaped coplanar waveguide microwave resonators for single cell detection, flow rate measurements, and nanopore sensing of viruses
(Bilkent University, 2020-09)Measurement sensitivity of different biosensing applications can be enhanced by using the microwave resonators. In the first application, microwave sensors based on bow tie shaped coplanar waveguide (CPW) resonator was ... -
Design of an X-band GaN based microstrip MMIC power amplifier
(Bilkent University, 2019-02)RF power amplifiers are crucial components of modern radar and communication systems. However, their design poses some challenges due to device limitations in high power and high frequency regime, as well as inherent ... -
Dropping of electromagnetic waves through localized modes in three-dimensional photonic band gap structure
(AIP Publishing, 2002-12-03)We experimentally demonstrate trapping and dropping of photons through localized cavity modes in three-dimensional layer-by-layer photonic crystal structures. By creating acceptor- and donor-like cavities which are coupled ... -
Fast algorithms for digital computation of linear canonical transforms
(Springer, New York, 2016)Fast and accurate algorithms for digital computation of linear canonical transforms (LCTs) are discussed. Direct numerical integration takes O.N2/ time, where N is the number of samples. Designing fast and accurate ... -
Implementation of high quality-factor on-chip tuned microwave resonators at 7GHz
(WILEY, 2009)We report on the design, analytical modeling, numerical simulation, fabrication, and experimental characterization of chip-scale microwave resonators that exhibit high quality-factors (Q-factors) in the microwave frequency ... -
Particle sensing with narrowband microwave split-ring resonators
(Bilkent University, 2021-09)A new microwave sensor with concentric split-ring resonator (CSRR) topology is designed and integrated with microfluidics. While the resonator is being driven at its resonant frequency, cells passing through the channel ... -
A planar metamaterial: Polarization independent fishnet structure
(Elsevier BV, 2008)We numerically and experimentally investigate a planar metamaterial that is composed of connected cut-wire pairs and continuous wires operating at 21 GHz. The characterization was performed by using the effective medium ...
