CG-FFT method proposed by Bojarski in 1971 was historically the very first known fast algorithm to reduce computational complexity and memory of MoM dense matrix equation solution from O(N²) to O(N lo...
An H2-matrix is a structured matrix but general enough for representing both PDE and IE operators in electromagnetic analysis. An example is the matrix resulting from a fast multiple method (FMM) base...
In this work, I will overview the recent development of butterfly algorithms for constructing fast iterative and direct solvers for high-frequency integral and differential equations in electromagneti...
RF Surface Acoustic Wave (SAW) resonators are paid much attention also for their use in scientific research such as qubit and spin control in addition to consumer applications. Only one metal layer is...
As 5G technology advances, there is a growing emphasis on acoustic wave (AW) devices that operate at frequencies above 10GHz and exhibit high electromechanical coupling coefficients (K2). This present...
We describe new strategies to access ultrahigh-coherence phonon modes within bulk acoustic wave resonators for use in both quantum optics and circuit QED. Efficient access to phonons with long coheren...
In this talk I will discuss my group’s progress toward a new class of classical microwave frequency phononic devices created by heterogeneously integrating semiconductors and piezoelectric materials. ...
Quantum computers have demonstrated potential to solve problems that are intractable for classical computers. Although current state-of-the-art quantum processors have shown promising results, they ha...
Acoustic waves are well-suited for a variety of signal processing applications including RF filtering and optical modulation. Advances in material and fabrication capabilities have enabled the demonst...
Thermal dissipation and heating limit the performance of many state-of-the-art electronic, MEMS, and acoustic devices and integrated circuits. Full-field thermoreflectance imaging measures the dynamic...
