Practical method for determining inductance and capacitance of metamaterial resonators
A practical approach to determining the distributed capacitance and inductance of individual metamaterial resonators is demonstrated. By loading a set of lumped capacitors onto the resonator, the resonance frequency can be measured as a function of the load capacitance. The capacitance and inductance values of the resonator are then determined by relating the equivalent circuit model to the mea...
متن کاملDouble-negative acoustic metamaterial.
We show here the existence of acoustic metamaterial, in which both the effective density and bulk modulus are simultaneously negative, in the true and strict sense of an effective medium. Our double-negative acoustic system is an acoustic analogue of Veselago's medium in electromagnetism, and shares many unique consequences, such as negative refractive index. The double negativity in acoustics ...
متن کاملNegative acoustic index metamaterial
Acoustic metamaterials utilizing periodic deep subwavelength resonators can attain negative acoustic properties unavailable in nature. We have developed a negative acoustic index metamaterial for water that combines Helmholtz and rod-spring resonators to control effective bulk modulus and mass density, respectively. Effective properties extracted from full-wave simulations of our metamaterial s...
متن کاملFast Inductance Extraction of Large VLSI Circuits
Accurate estimation of signal delay is critical to the design and verification of VLSI circuits. At very high frequencies, signal delay in circuits with small feature sizes is dominated by the parasitic inductance and capacitance of the interconnect. Inductance extraction involves the solution of large, dense, complex linear systems of equations by preconditioned iterative methods. Fast inducta...
متن کاملBandwidth Enhancement of Metamaterial loaded Microstrip Antenna using Double Layered Substrate
Communication has become a key aspect of our daily life, becoming increasingly portable and mobile. This would need the use of micro strip antennas. The rapid growth has led to the need of antennas with smaller size, increased bandwidth and high gain. In this paper, a new version of micro strip patch antenna is designed by adopting double layered substrate concept and adding a layer of metamate...
