This document outlines the agenda for a lecture on microwave devices, including revisiting the ABCD matrix, discussing microwave resonators, series and parallel resonant circuits, and transmission line resonators. Key topics covered are the ABCD relation to impedance matrix, microstrip excitation and network model, characteristics of series and parallel resonant circuits including quality factor and bandwidth, and types of transmission line resonators such as short-circuited λ/2 lines.
Microwave Devices Lecture05
This document discusses network analysis techniques for microwave circuits. It covers impedance and equivalent voltages and currents, including intrinsic, waveguide and characteristic impedances. Impedance and admittance matrices are introduced for analyzing microwave networks. The scattering matrix is presented as another method to analyze circuits based on incoming and outgoing wave relations. An example scattering matrix is also provided.
Microwave Devices Lecture02
This document discusses planar electromagnetic waves in different media. It covers:
1) Deriving the Helmholtz equation and solutions for planer waves in lossless and lossy media.
2) Defining skin depth and solutions for waves in good conductors.
3) Discussing general solutions to the planer wave equation.
4) Defining linear and circular polarization of planer waves.
5) Calculating energy, power, and the Poynting vector for planer waves.
6) Defining reflection and transmission coefficients at boundaries between different media.

How to Make a Field Mandatory in Odoo 17
In Odoo, making a field required can be done through both Python code and XML views. When you set the required attribute to True in Python code, it makes the field required across all views where it's used. Conversely, when you set the required attribute in XML views, it makes the field required only in the context of that particular view.

Temple of Asclepius in Thrace. Excavation results
The temple and the sanctuary around were dedicated to Asklepios Zmidrenus. This name has been known since 1875 when an inscription dedicated to him was discovered in Rome. The inscription is dated in 227 AD and was left by soldiers originating from the city of Philippopolis (modern Plovdiv).
