Total internal reflection fluorescence microscopy (TIRF), in both commercial and custom-built configurations, is widely used for high signal-noise ratio imaging. The imaging depth of traditional TIRF is sensitive to the incident angle of the laser, and normally limited to around 100 nm. In our paper, using a high refractive index material and the evanescent waves of various waveguide modes, we ...

The recently discovered kagome superconductor CsV$_3$Sb$_5$ ($T_c \simeq 2.5$ K) has been found to host charge order as well a non-trivial band topology, encompassing multiple Dirac points and probable surface states. Such complex phenomenologically rich system is, therefore, an ideal playground for observing unusual electronic phases. Here, we report on microscopic studies of its anisotropic s...

The factors in the drag equation (that is, the coefficient of drag, the density of the medium, and the cross-sectional area and velocity of the projectile) also determine the depth that a projectile will penetrate its target and the velocity of the projectile at a given depth of penetration. Ideally (that is, if a stable, nondeforming projectile passes through a homogeneous, infinite solid), th...

investigation of projectiles penetration phenomenon has been carried out in non-cohesive soil (sand) targets under dry, saturated and compacted conditions. analytical studies have been performed on the linear and non-linear soil models to obtain penetration depth formulae for ogival nose projectile and the results are verified by experimental studies. in present work, three ogival nose projecti...

We use prior theory and experimental results to construct a quantitative relationship between soil moisture and the penetration depth of synthetic aperture radar (SAR) microwaves at L-, C-, and X-bands. This relationship is nonlinear and indicates that a change of 5% volumetric water content (VWC) can cause between 1 and 50 mm of change in C-band penetration depth depending on initial VWC. Beca...

A new dimensionless relationship for analysis of ballistic penetration data is derived and applied to polycrystalline ceramic materials. Targets consist of ceramic tiles backed by thick metallic plates within which residual penetration depths have been reported in experimental studies. Particular ceramics analyzed here are lowand high-purity alumina, aluminum nitride, boron carbide, silicon car...
