“…At this stage the reflection and the transmission coefficients come into play, where these pulses either get transmitted or reflected. Generally, heat diffusion problems are addressed in a wide range of applications, such as semiconductor lasers, power semiconductor devices, and optoelectronics [16,18,[22][23][24][25][26][27]. Recently, the TLM method was used in [28] to solve the problem of transient heat transfer in inhomogeneous Thermal radiation using TLM method 3 arrangements of interconnects and dielectrics.…”

 Abstract-In this paper, the use of the Transmission Line Matrix (TLM) method for the treatment of thermal effects in nanoscale systems is discussed. A new approach is presented, which combines the modeling of thermal diffusion and radiation effects using emissivity in a one dimensional TLM model. The work shows the suitability of using TLM to model heat dissipation in nanoscale engineering components. It offers an appropriate solver for thermal applications, such as heat dissipation, in nanodevices. Two types of nanowires are simulated to demonstrate the behavior of the proposed approach.

“…This technique uses Huygens' principle and is based on Maxwell's equations [11,22,24,25]. It operates on a mesh structure where each element is represented by a transmission line that acts as an analogy between the physical quantity and an electrical equivalent (voltage or current) [20,[24][25][26].…”

Numerical modeling has become an indispensable tool for solving various physical problems. In this context, we present a model of pollutant dispersion in natural streams for the far field case where dispersion is considered longitudinal and one-dimensional in the flow direction. The Transmission Line Matrix (TLM), which has earned a reputation as powerful and efficient numerical method, is used. The presented one-dimensional TLM model requires a minimum input data and provides a significant gain in computing time. To validate our model, the results are compared with observations and experimental data from the river Severn (UK). The results show a good agreement with experimental data. The model can be used to predict the spatiotemporal evolution of a pollutant in natural streams for effective and rapid decision-making in a case of emergency, such as accidental discharges in a stream with a dynamic similar to that of the river Severn (UK).

A 2D transmission line matrix model is used to study thermal transfer in living tissues exposed to laser energy. Damage size because of thermal coagulation in thermal treatment of benign prostate hyperplasia is determined quantitatively. Results show a quasilinear dependency of blood perfusion on temperature at the beginning of coagulation. Immediately thereafter, blood perfusion decreases considerably until it shuts down when the tissue under investigation has been coagulated. Increase in perfusion rate (ω) leads to high values of t 100 , which is the time required to reach a primary zone temperature of about 100°C, and reflects the increased cooling created by perfusion. The transmission line matrix numerical model predicts the coagulation damage contours; that way, it has a clinical interest in therapy as an aid for clinicians because damage cannot be easily measured within patients. Results are validated through comparison with other researches.
