Propagation of Waves

Propagation of Waves

When a wave propagates from one medium to another, part of it may get reflected in the first medium, and part of it may get transmitted to the second medium. In such a case, the interface of the two mediums can be considered as a boundary that is neither fixed nor free.
Consider a scenario where a wave propagates from a string of low linear mass density to a string of high linear mass density. In such a case, the reflected wave is out of phase with respect to the incident wave, however the...

Reticular Dermis

Reticular Dermis

The papillary and reticular dermis are the two layers of the dermis. They are made of connective tissue with fibers of collagen extending from one to the other, making the border between the two somewhat indistinct. The dermal papillae extending into the epidermis belong to the papillary layer, whereas the dense collagen fiber bundles below belong to the reticular layer.
Reticular Layer
Underlying the papillary layer is the much thicker reticular layer, composed of dense, irregular connective...

Layers of the Epidermis

Layers of the Epidermis

The epidermis, the outermost layer of the skin, is composed of several distinct layers. From deep to superficial, the layers of the epidermis are as follows:
Stratum Basale
Stratum basale, also known as the stratum germinativum, is the deepest layer of the epidermis. It is composed of a single layer of actively dividing cells called basal cells or basal keratinocytes. These cells constantly undergo cell division to replenish the upper layers of the epidermis. Additionally, melanocytes, which...

Biomedical Optics
Mathematical Modeling
Light Propagation in Tissues

Background:

Light propagation in biological tissues is complex, influenced by tissue structure.
Modeling light interaction with layered tissues is crucial for diagnostic and therapeutic applications.
Irregular interfaces between tissue layers, like epithelium and stroma, pose challenges for accurate modeling.

Purpose of the Study:

To develop a model for light propagation in a two-layered half-space with an irregular interface.
To provide an asymptotic approximation for light propagation under specific interface conditions.
To establish a method for reconstructing irregular tissue interfaces from optical measurements.

Main Methods:

Formulating the problem of light propagation in a two-layered medium.
Applying perturbation theory to approximate solutions for small interface irregularities.
Developing a numerical method to compute the asymptotic approximation.
Utilizing boundary measurements to invert the model and recover interface geometry.

Main Results:

An asymptotic approximation for light propagation through irregular two-layered media was derived.
A numerical method was successfully developed to compute this approximation.
The study demonstrated the feasibility of reconstructing irregular interfaces using optical boundary data.

Conclusions:

The developed model and methods provide a viable approach for analyzing light propagation in complex biological tissues.
Reconstruction of irregular interfaces from boundary measurements is achievable when optical properties are known.
This work contributes to understanding light-tissue interactions for potential biomedical applications.
