The high and low voltage balancing operation across the DC bus capacitor hasbeen very challenging for SST configuration especially for parallel-connected DAB and multi-port application [15]. In this paper, a d-q vector control-based DC voltage and load voltagebalancing technique for both rectifier and inverter stages are presented. A simple classic d-qvector controller is applied in this system.Rectifier StageThe high voltage grid is connected to the front end of the SST that is

Results & DiscussionNanostructures, such as dolmens and oligomers of nanoparticles as well as several plasmonicmetasurface structures, have shown to exhibit Fano resonances in the optical domain. An example ofsuch nanostructure is the ultrathin Babinet-inverted metasurface made up of asymmetric split-ringapertures fabricated in a metal plate, which produces high-quality-factor (high-Q) Fano resonances. TheFano resonances originate from the interaction of bright modes and dark modes that give rise toasymmetric linewidth profiles in the scattering parameters, such as absorption or reflection spectra.

This ∆f can be interpreted as the width of a frequency bin that is centered onfcent. The smaller the width of the bin, the higher the resolution of frequency. It is important tonote that changing the sample size or sampling rate will change the resolution, and that changingsampling rate alone modifies both the Nyquist cut-off frequency and the center frequency.

We had to reevaluate our thinking process and convert the code block by block. The conversion of an idea was much easier to implement than converting a line of code. Once we understood the methodology behind a chunk of code, it was relatively straightforward to express that idea in Mathematica’s syntax…. The reason why this process was straightforward was due to our knowledge of Mathematica on an intermediate level.”q “The Maple code was not very helpful as a template.
