When embedded in a time domain electromagnetic field simulator, these models provide a versatile CAD tool and computational test bed for media with negative refractive index. Simulation results validate these TLM models and demonstrate their capabilities and potential....

Guided Modes in a Waveguide Filled With a Pair of Single-Negative (SNG), Double-Negative (DNG), and/or Double-Positive (DPS) Layers Here we present the results of our theoretical analysis for guided modes in parallel-plate waveguides filled with pairs of parallel layers made of any two .....
which are discussed in the following section. Additionally, they have compiled extensive metric that encompass various key parameters, such as aggregation structure, refractive index, and particle size dimensions (including both the size of individual microcrystallites and their number in soot particles)...
It is a specific instance of three wave-mixing processes in which the frequency of each of the three photons could be different, i.e., \(\omega _1 \pm \omega _2 = \omega _3\)where the positive sign corresponds to the sum-frequency generation (SFG) and the negative sign to the ...
Weights for each surface point are computed via non-negative matrix factorization (NMF), based on data that is densely acquired from 15 views and 300 light directions. These methods assume only isotropic reflectance and acquire much denser key measure- ments than we do (by 1-2 orders of ...
In tumor therapy anti-angiogenic approaches have the potential to increase the efficacy of a wide variety of subsequently or co-administered agents, possibly by improving or normalizing the defective tumor vasculature. Successful implementation of the co
{rel}}}\)with its strongly pronounced maximum is decisive for optimizingλdesign. Nevertheless, the LDOS effect needs to be considered when regarding a particular irradiance. As demonstrated in Fig.3c, the altered LDOS has a negative effect at low irradiances and a positive effect at high ...
, will be different in this plane and that there will always be equal numbers of positive and negative -orders. COMSOL will automatically compute these order modes during the set-up of a Periodic Port and define listener ports so that it is possible to evaluate how much energy gets diffracted...
