This document contains exam questions about antenna engineering parameters for a Hertzian dipole antenna operating at 13 GHz. The questions ask the examinee to: (1) calculate the E-field, H-field, radiation power, resistance, and input impedance at given distances and angles from the antenna; (2) draw the input impedance on a Smith chart; and (3) compare resonance characteristics of Hertzian and half-wave dipole antennas without using formulas. An additional question asks the examinee to explain electromagnetic wave radiation by a antenna in terms of current density and vector potential without using textbook formulas.
The document discusses the functions f(t)=A sin (Bt + C) and f(t)=A cos (Bt + C), explaining that they require an amplitude (A), period (determined by B), and phase shift (C) to define the wave pattern.

How to Manage Reception Report in Odoo 17Celine George
A business may deal with both sales and purchases occasionally. They buy things from vendors and then sell them to their customers. Such dealings can be confusing at times. Because multiple clients may inquire about the same product at the same time, after purchasing those products, customers must be assigned to them. Odoo has a tool called Reception Report that can be used to complete this assignment. By enabling this, a reception report comes automatically after confirming a receipt, from which we can assign products to orders.
