The design of matching media with different dielectric constants for the use in implant communications is presented in this paper. Each medium consists of a three-dimensional printed honeycomb structure filled with a high dielectric lossless semi-liquid. The dielectric constant of the media is determined by the infill percentage of the honeycomb structure as well as the dielectric constant of both the semi-liquid and the material of the structure. An algorithm is developed that can specify values for the infill percentage to reach a target dielectric constant value from a given material and semi-liquid. For the measurements, several honeycomb structures with different infill percentages are fabricated with polylactic acid using additive manufacturing. Water-based semi-liquids are developed to fill the structures. The dielectric constants of the fabricated media are measured with a half-filled rectangular resonant cavity. The practical results indicate that target dielectric constants ranging from 8 to 34 are reached by using semi-liquids with dielectric constants ranging from 20 to 65 between 2.2 GHz-3.2 GHz. The practical results are also shown to be in good agreement with the numerical ones with an error of less than 9% for all different cases.

High-frequency CMUT arrays for high-resolution medical imaging
Oralkan, O; Hansen, ST; Bayram, Barış; Yaralioglu, GG; Ergun, AS; Khuri-Yakob, BT (2004-01-01)
This paper describes high-frequency I-D CMUT arrays designed and fabricated for use in electronically scanned high-resolution ultrasonic imaging systems. Two different designs of 64-element linear CMUT arrays are presented in this paper. A single element in each array is connected to a single-channel custom front-end integrated circuit for pulse-echo operation. The first design has a resonant frequency of 43 MHz in air, and operates at 30 MHz in immersion. The second design exhibits a resonant frequency of ...
Multi-band metamaterial absorber topology for infrared frequency regime
Mulla, Batuhan; Sabah, Cumali (2017-02-01)
In this paper, a new multiband metamaterial absorber design is proposed and the numerical characterization is carried out. The design is composed of three layers with differently sized quadruplets in which the interaction among them causes the multiband absorption response in the infrared frequency regime. In order to characterize the absorber. and explain the multiband topology, some parametric studies with respect to the dimensions of the structure are carried out and the contributions of the quadruplets ...
Dynamic FEM analysis of multiple cMUT cells in immersion
Bayram, Barış; Ergun, AS; Oralkan, O; Khuri-Yakub, BT (2004-01-01)
This paper reports on the accurate modeling of immersion capacitive micromachined ultrasonic transducers (cMUTs) using the time-domain, nonlinear finite element package, LS-DYNA, developed by Livermore Software Technology Corporation (LSTC). A capacitive micromachined ultrasonic transducer consists of many cMUT cells. In this paper, a square membrane was used as the unit cell to cover the transducer area by periodic replication on the surface. The silicon membrane, silicon oxide post and insulation layer we...
A dielectrophoretic cell/particle separator fabricated by spiral channels and concentric gold electrodes
Yilmaz, G.; Çiftlik, A.T.; Külah, Haluk (2009-12-14)
This paper presents the design and implementation of a novel dielectrophoresis (DEP) system with spiral channels and concentric electrodes for high resolution cell separation applications. The device is fabricated with a 4 mask parylene process and the design is optimized in MATLAB Simulink reg to confine the operation. Tests with micro particles of different sizes are performed to show size-based separation by dielectrophoresis. Proposed device is also tested with K562 leukemia cell lines to prove that the...
Fabrication of a Three-Axis Capacitive MEMS Accelerometer on a Single Substrate
Aydemir, Akin; Akın, Tayfun (2015-11-04)
This paper presents a new fabrication approach and a design for the fabrication of a three-axis capacitive MEMS accelerometer where differential sensing is enabled for all sense directions. In this approach, individual lateral and vertical axis accelerometers are fabricated in the same die on an SOI wafer which is eutectically bonded to a glass substrate. Differential sensing for the vertical axis accelerometer is realized by defining the proof mass of the accelerometer on the structural layer of the SOI wa...
